Abstract: Blends of polypropylene and nylon-1010 in 50 : 50 ratio were prepared using a polyethylene-based ionomer as a compatibilizer.The effects of the addition of this compatibilizer on the morphology,melting and crystallization behavior and the dynamic mechanical properties of the blends were examined. The compatibilization of the ionomer in the blends was measured. The size of dispersed particles reduced in PPlnylon1010 lionomer blends. The crystallization temperatures,melting points and the degree of crystallinity of polypropylene were decreased by the addition of ionomer.

Key words: nylon-1010, polypropylene, ionomer, compatibility
