Blends of isotactic polypropylene (iPP) with the polyamide nylon-6 (N6), prepared by extrusion, were studied with a composition of up to 30% by weight polyamide. In the case of a 70/30 iPP/N6 blend, the influence of a compatibilizing agent based on polypropylene functionalized with maleic anhydride
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
## Abstract Morphology development during the coalescence under shear in polypropylene/polystyrene blends was studied in this article. The coalescence was performed by decreasing the shear rate after a fine morphology is obtained at higher shear rate. Time resolved SEM performance indicates that, b
