摘要

正

Differential scanning calorimetry and X-ray diffraction experiments on β-nucleated polypropylene were made on the samples crystallized at different temperatures and processed by injection molding. The crystal perfection was shown to vary with crystallization temperature. The observed multiple peaks could be related to a ill-phase with defective inclination of the chains

a recrystallized or original β

-phase of more perfect inclination

and the α-phase. Injection molded samples could be analyzed from the established DSC interpretation.
