Abstract:
A study is reported of the anomalous glass transition temperature, Tg, in thin free-standing conjugated polymer films revealed by confocal Raman scattering. Full details of the dependence of Tg on film thicknesses d ranging from less than to greater than the polymer average end-to-end distance REE are presented. In contrast to ultrathin films (d

Polymer Classification: Crystallinity
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...
Polymers: Molecular Weight Distribution
Molecular Weight of Step-Growth Polymers
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.
The extent of the...
