Novel polypropylene based microporous membranes via spherulitic deformation
… T 2 appears to be the result of the rigid amorphous fraction trapped within "lamellar wells" where the amorphous phase is surrounded by R-lamellae and T-lamellae. The lamellae could break down or slip from the lamellar knots as stretching temperatures are high enough to minimize the …

Morphology, Crystallization and Melting Behavior of Propylene-Ethylene Statistical Copolymers
… inadequacies were found in application of the rigid amorphous fraction model to these copolymers. The formation of gamma-phase crystals was shown to be favored by both an increase in the ethylene content and a decrease in the crystallization rate. Increase in the ethylene content was shown to …

Crystallization Behavior of Bisphenol-A Polycarbonate: Effects of Crystallization Time, Temperature, and Molar Mass
… the feasibility of obtaining near monodisperse fractions provide distinct advantages for the elucidation of the effects of crystallization time, temperature, and molar mass on crystallization kinetics. The effects of molar mass on the glass transition temperature (Tg) and heat capacity change at …
