## Abstract Melting‐point and spherulite growth rate measurements for a sample of syndiotactic polypropylene (__S__ = 0.716 and η = 0.356) were analyzed for the parameters characterizing crystal formation and growth: __T__~__m__~ = 159 ± 2°C, σ~__e__~ = 47 erg cm ^−2^, σ = 4.4 erg cm^−2^, and __q__
In order to analyse the effect of small additions (up to 20 wt%) of low-density polyethylene (LDPE) on the crystallization kinetics and thermodynamics of an isotactic polypropylene (iPP), morphological studies of iPP/LDPE blends have been carried out. The results have shown that at LDPE percentages
