X, I believe you are referring to the Lightwave SHM slide #14, see link below and scroll until that graph.

You will notice this slide talks about "LWLG EO polymers are uniquely resistant to de-poling due to high Tg"

I did my own further AI searches to better understand Tg, and also included the search word "diamondoids" as my past research on that petroleum complex carbon chain product was very revealing on how diamondoids can stabilize the polymers that have been poled as they operate. That search was prompted by the LWLG Jan 2022 Diamondoids patent registration. The AI search is further below.

AI Overview
Yes, incorporating diamondoids into polymers can lead to a significant increase in the glass transition temperature (Tg).

Here's why:

Steric hindrance: Diamondoids are bulky, rigid cage-like molecules. When introduced as pendant groups or into the polymer backbone, they hinder the rotational and segmental motion of the polymer chains.

Reduced chain mobility: Restricted chain movement means that a higher temperature (thus a higher Tg) is required to overcome these restrictions and allow the polymer to transition from a rigid, glassy state to a more flexible, rubbery state.
Increased stiffness: This restricted mobility also translates into increased chain stiffness, which further contributes to a higher Tg.

Enhanced intermolecular forces: Depending on the specific diamondoid and polymer, diamondoids can also increase intermolecular forces, further limiting chain mobility and boosting Tg.

Examples
Copolymers containing adamantyl methacrylate showed improved Tg and mechanical properties.
Polyamides incorporating 1,6- or 4,9-diamantylene groups exhibited improved thermal stability and retained their storage modulus at temperatures above 350°C.

The Tg of poly(alpha-arylTMC)s could be varied significantly by modifying the pendant groups with bulky naphthyl rings, showing a Tg of 97 °C with a bromo-naphthyl pendant group, a 117°C improvement over poly(TMC).

In summary
Diamondoids, due to their bulky structure, can effectively restrict the movement of polymer chains, leading to a higher glass transition temperature and enhanced thermal stability and mechanical properties.

Now lets add Lightwave Logic into that same question about diamondoids and see what happens.

AI Overview

Yes, Lightwave Logic's patent filings indicate that incorporating diamondoid groups into their chromophores contributes to increased stability when these chromophores are dispersed within a host polymer matrix. One aspect of this increased stability, and directly related to the question of High Tg, is that the material retains its electro-optic properties more robustly after being "poled", a process that typically involves heating the polymer above its Tg to align the chromophores before cooling it back down.

While the patent language specifically highlights improved stability rather than directly stating an increase in Tg, other research on the effects of diamondoids in polymers, including adamantane (the smallest diamondoid), supports the idea that diamondoids can increase the Tg and thermal stability of polymers.

Therefore, it can be inferred that the inclusion of diamondoid groups in Lightwave Logic's electro-optic polymers likely contributes to a high Tg, which is beneficial for the long-term performance and reliability of their devices.

Now lets look at Lightwave's most recent, and also stock moving (9+ mil volume first 2 days after PR) Press Release to understand why recent news was very important as it relates to Passes Telcordia 85/85 Test & Develops Enhanced Moisture & Oxygen Resistance via Fourth-Generation Encapsulation Technology which is all about their ongoing advancement of their ALD patent which they bought a few years ago, and boy, was that acquisition KEY! 🚀💯😎

ENGLEWOOD, COLORADO / ACCESS Newswire / July 15, 2025 / Lightwave Logic, Inc. (NASDAQ:LWLG) (the "Company"), a leading provider of high-performance electro-optic (EO) polymer materials, today announced that its latest-generation Perkinamine™ polymer has successfully passed the rigorous Telcordia GR-468 85/85 environmental stress test (85 °C at 85 % relative humidity), validating its long-term reliability under harsh environmental conditions. The results confirm that Lightwave Logic's EO polymer materials can maintain performance over time, meeting key industry requirements for deployment in telecom and datacom infrastructure.


Expanded 85/85 Test Results:

Sample selection: Thin-film devices with second-generation proprietary encapsulation barrier

Stress conditions: 85 °C and 85 % relative humidity for 1,000 hours

Performance: Change in absorbance measurements showed only 1.6% average loss after 1,000 hours

Pass rate: More than 11 samples exceeded Telcordia GR-468 requirements by a wide margin

These results highlight robust protection against moisture and oxygen, enabled by Lightwave Logic's proprietary encapsulation technology.

And then you post after our recent huge rigorous Telcordia GR-468 85/85 environmental stress test (85 °C at 85 % relative humidity) for 1000 hours..........

100 year performance at 85c

I hope you understand the Telcordia GR-468 85/85 environmental stress test is a much different test than the Tg and Top for the 85 C and 175 C up to 100 years as that Slide 14 showed. Below is a helpful AI overview search that might help better understand these differences. And don't forget, "units matter"! 😎

AI Overview

Lightwave Logic's latest-generation Perkinamine™ polymer, in combination with advanced encapsulation technology, demonstrates significant reliability, particularly at higher temperatures, for applications requiring long-term stability.

Here's how it relates to your question:

85°C Operating Temperature: Lightwave Logic's Perkinamine™ polymer has successfully passed the Telcordia GR-468 85/85 environmental stress test, which involves exposure to 85°C at 85% relative humidity for 1,000 hours, showing only a 1.6% average loss of absorbance. This demonstrates its ability to maintain performance at 85°C, meeting key industry requirements for deployment in telecom and datacom infrastructure.

High Tg (Glass Transition Temperature): Lightwave Logic specifically highlights the high glass transition temperature (Tg) of their polymers as a critical factor for achieving long-term stability and eliminating the need for cross-linking, especially when operating close to industry specification high limits. While a specific Tg of 175°C is mentioned in a related context (linking to potential 100-year lifetime at 85°C), the company also emphasizes that their polymers have a Tg significantly above the industry specification of 0-85°C.

100-Year Lifetime at 85°C: One document, referencing LWLG data, directly shows a relationship where a polymer with a Tg of 175°C operating at 85°C could potentially offer a 100-year lifetime. It also states that increasing Tg significantly increases lifetime at 85°C, with a polymer having a Tg of 160°C demonstrating >108 times greater lifetime at 85°C compared to a polymer with a Tg of 90°C, according to Lindsay's time constant formula.

Therefore, based on the provided information, Lightwave Logic's polymers are designed with a high Tg to achieve long-term reliability at temperatures such as 85°C, and they have successfully passed industry-standard tests (Telcordia 85/85) supporting this claim. While the 100-year lifetime is presented in a context that correlates with a 175°C Tg and an 85°C operating temperature, it's important to remember that such claims are typically based on accelerated aging tests and modeling.
