Thermodynamics and Kinetics of Syndiotactic Polystyrene

It is important to establish the equilibrium melting point as accurately as possible because the crystallization parameters derived from the kinetic data are rather sensitive to T . Thus, T has carefully been established from the dependence of the melting point on the fold thickness.

The characteristics of the sample used are M = 1.9 x 10 g/mol, Mw/M = 2.5, and [rrrr] 95mol%.The light scattering apparatus for the measurements was especially constructed in the laboratory. 

The radial growth rates of polymeric spherulites are expressed as a function of undercooling from their equilibrium melting point according to the well-known equation of Hoffman and Lauritzen [4,5], 

The first exponential term contains the contribution of the diffusional process to the growth rate and it is closely analogous to the segmental jump
