Optical microscopy, differential scanning calorimetry, and small-angle X-ray scattering techniques were used to study the influence of crystallization conditions on the morphology and thermal behavior of samples of ternary blends constituted by isotactic polypropylene (iPP), atactic polystyrene (aPS

The crystallization and morphology of reactor-made blends of isotactic polypropylene ( PP ) with a large content of ethylene -propylene rubber ( EPR ) (i.e., ΓΊ 50%) were investigated. In the blends, PP was found to form spherulites during the crystallization process, with the growth rate constant un
A novel graft copolymer of unsaturated propylene with styrene (uPP-g-PS) was added to isotactic polypropylene (iPP) to investigate the state of mixing between uPP-g-PS and iPP phase and effects of the uPP-g-PS addition on iPP intrinsic phase structure, i.e., on iPP spherulitic texture and inner stru
