THERMOPLASTIC POLYOLEFIN COMPOSITIONS HAVING IMPROVED MELT VISCOSITY AND METHODS OF MAKING THE SAME

摘要

Disclosed is a thermoplastic polyolefin composition having a reduced melt viscosity, (a) polypropylene, (b) a hydrogenated copolymer of a vinyl aromatic compound and an alkylene compound, comprising (i) from 1 to no more than 30% by weight of vinyl aromatic residues, based on the weight of the copolymer, and (ii) at least 60 % by weight of alkylene residues that are C 4 or higher, based on the weight of the copolymer, and a processing oil (f).
