## Abstract Meltingβpoint and spherulite growth rate measurements for a sample of syndiotactic polypropylene (__S__ = 0.716 and Ξ· = 0.356) were analyzed for the parameters characterizing crystal formation and growth: __T__~__m__~ = 159 Β± 2Β°C, Ο~__e__~ = 47 erg cm ^β2^, Ο = 4.4 erg cm^β2^, and __q__
In previous work we have shown that the stable form of syndiotactic polypropylene (sPP) adopts a fully antichiral packing in its crystalline lattice. At the same time, we had also discovered a number of prohibited reflections from crystallographic planes with a c-axis component, indicating distortio
Crystallization in syndiotactic polypropylene was investigated using Monte Carlo methods to generate polymer chains having sequences with representative stereochemistries. The chains were then slid by one another in parallel arrangements to look for matches that could lead to crystallite formation.
