<P>PROBLEM TO BE SOLVED: To provide thermoplastic polyolefin compositions having reduced melt viscosities at a given temperature and more specifically thermoplastic polyolefins for rotational molding requiring lower processing temperatures. <P>SOLUTION: The thermoplastic polyolefin composition contains (a) polypropylene, (b) a hydrogenated copolymer of a vinyl aromatic compound and an alkylene compound, comprising (i) from 1 to no more than 30 wt.% of vinyl aromatic residues, based on the weight of the copolymer, and (ii) at least 60 wt.% of alkylene residues that are C<SB POS="POST">4</SB>or higher, based on the weight of the copolymer, and a processing oil (f). <P>COPYRIGHT: (C)2013,JPO&INPIT |
