## Abstract **Summary:** Two wellβcharacterized metallocene isotactic poly(propylene) (iPP) samples, one of high and one of low molecular weight, were blended together for studying the effects of a second component on quiescent and shearβinduced crystallization. A small amount of added high molecul
Thermal fractionation techniques offer quick and practical ways to evaluate chain heretogeneities in semicrystalline thermoplastic materials by employing carefully designed thermal cycles in a Differential Scanning Calorimeter (DSC). They are particularly useful to study the degree and distribution
