The selection of polymers is done on the basis of glass transition temperature, those with higher glass transition temperature are selected. We evaluate the ease of synthetic accessibilities of the selected polymers alongwith their structural variations which indicates a diverse range among them. ...
On the other hand, there is a need for aromatic high glass transition temperature polymers,such as polysulfone, polyethersulfone, and polyphenylsulfone, suitable to be used in applications where extractableionics must be minimized, like in sensitive electronics applications such as the semiconductor ...

Local glass transition temperature Tg(z) of polystyrene next to different polymers: Hard vs. soft confinement The depth to which the local glass transition temperature T g and alpha-relaxations are perturbed near a boundary is believed to be related to the characteristic length scales associated wit...
Shape-memory polymers (SMPs) aresynthesized with adjustable glasstransition temperature ( T g ) ranging from299 to 322 °C, higher than those reported previously. The polyimidecontaining thermal stable but flexible linkages within the backboneact as reversible phase, and high molecular weight ( M n...
(μ)25,26,27. However, the small molecules may also act as plasticizer by weaken the interaction between polymer chains, resulting in degraded structural thermal stability of polymer dielectrics which is usually reflected by sharply decreased glass transition temperature (Tg)28. As a result, the ...
glass transition temperatureshigh pressure DSCThe glass transition temperatures of polycarbonate (PC) were measured by means of high pressure DSC in He, N 2 , and CO 2 atmospheres. It was found that the glass transition temperature ( T g ) of PC was independent in He with pressure up to ...
