Machine learning glass transition temperature of polymers [PDF]

open access: yesHeliyon, 2020
As an important thermophysical property, polymers' glass transition temperature, Tg, could sometimes be difficult to determine experimentally. Modeling methods, particularly data-driven approaches, are promising alternatives to predictions of Tg in a ...

Effects of steaming treatment on crystallinity and glass transition temperature of Eucalyptuses grandis × E. urophylla

open access: yesResults in Physics, 2017
To investigate the effects of steaming treatment on crystallinity and glass transition temperature, samples of Eucalyptuses grandis × E. urophylla with moisture content of 50%, 70%, and 90% were steamed in saturated steam at 100 °C for 2, 4, 6, and 8 h ...

The glass transition temperature investigation of polymers by molecular dynamic simulations

open access: yesҚарағанды университетінің хабаршысы. Физика сериясы, 2023
In this paper, the process of glass transition is studied, the theory of which is not fully developed. Computer modeling can be used to understand the theory of this phenomenon. The glass transition temperature is influenced by a large number of polymer

Influence of Carbon Dioxide on the Glass Transition of Styrenic and Vinyl Pyridine Polymers: Comparison of Calorimetric, Creep, and Rheological Experiments

open access: yesAdvances in Polymer Technology, 2022
The glass transition of amorphous polymers determines the mobility of polymer chains and the time scale of relaxation processes. The glass transition temperature is reduced by the presence of low molecular weight molecules, e.g., dissolved gases or ...

Microscopic versus Macroscopic Glass Transition(s) in Blends of Industrial Interest [PDF]

open access: yesEPJ Web of Conferences, 2022
We investigate by neutron scattering and calorimetry a mixture of styrene-butadiene rubber (SBR) and a commercial resin. The neat materials present a large dynamic contrast, having SBR a much lower glass-transition temperature than the resin.

Entropy of Mixing and the Glass Transition of Amorphous Mixtures

open access: yesEntropy, 2008
Different equations have been proposed for estimating the glass transition temperature of amorphous mixtures. All such expressions lack a term to account for the effect of the entropy of mixing on the glass transition.

The structure and glass transition behavior of PLLA under the influence of gamma radiation [PDF]

open access: yesHemijska Industrija, 2010
The influence of gamma radiation on the structure and glass transition behavior of poly-L-lactide (PLLA) has been studied. Since PLLA exposed to high-energy radiation in the presence of air is prone to chain scission reactions and large degradation ...
