What is the glass transition temperature of polyethylene? Glass Transition Temperatures: Glass transition temperature only applies to amorphous solids, those that do not have a crystalline structure for their atoms or molecules. When they reach their glass transition temperature, the movement of the par...

The assignment of the glass transition temperature of polyethylene has been a matter of heightened controversy in recent years, and has formed the basis of several reviews [la-Id] as well as numerous original contributions. The controversy in polyethylene has also focused attention on other issues:...
“flexible” alkyl side chains. Although more flexible than the backbone, alkyl side chains are rather stiff, given that a dodecyl side chain is about one Kuhn length of polyethylene40. Nevertheless, based on the general trend that the backboneTgis higher for stiffer polymers with shorter alkyl ...
There are many different factors that affect a polymer’s glass transition temperature (Tg), including: Molecular Structure – Polymers with flexible molecular chains, such as polyethylene, tend to have lower Tg values. On the other hand, polymers with more rigid and inflexible molecular structures...
A novel transition appeared above the glass transition temperature of chlorinated polyethylene (CPE) for binary blends of CPE and additives such as organic... CF Wu - 《Chinese Journal of Polymer Science》 被引量: 63发表: 2001年 Pressure dependence of dielectric properties of chlorinated polyethylen...
Molecular dynamics simulations have been used to investigate the conformational transition behavior in amorphous polyethylene with different chain lengths across the glass transition temperature (Tg). In the present study, we examined the barrier height of conformational transition rates in different states....
