## Abstract Melting‐point 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, Οƒ~__e__~ = 47 erg cm ^βˆ’2^, Οƒ = 4.4 erg cm^βˆ’2^, and __q__

The crystallization from the melt of the trans-planar mesomorphic form of syndiotactic polypropylene is investigated at different quenching temperatures. The formation of the trans-planar mesomorphic form at 25, 0 and 6 8C is followed as a function of the residence time at these temperatures by X-ra

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.

The packing of the chains in (T 6 G 2 T 2 G 2 ) n conformation of the form IV of s-PP is revisited on the basis of packing energy and structure factor calculations. According to this analysis, an alternative mode of packing has been suggested. A monoclinic structural model, with the unit cell center
