Abstract

The addition of ethylene-propylene random copolymer (EPR) to polypropylene (PP) homopolymer and the synthesis of polypropylene/ethylene-propylene block-sequential copolymer (PP/E-P) have been developed in order to improve upon the mechanical properties of PP resin. The block-sequential polypropylene/ ethylene-propylene copolymer or the appropriate blend of EPR with PP gives improved impact properties without loss of elastic modulus [1–3].
