THERMOPLASTIC POLYOLEFIN COMPOSITIONS HAVING IMPROVED ADHESION TO POLYMER FOAMS AND/OR COATINGS AND METHODS OF MAKING AND USING THE SAME

摘要

Disclosed is a thermoplastic polyolefin composition having improved adhesion to applied polymeric foams or coatings, the composition comprising (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 55 % by weight of alkylene residues that are C4 or higher, based on total alkylene content of copolymer (b) prior to hydro genat ion, (c) a functionalized polyolefin, and (d) a monoamine terminated polyalkylene oxide. In one embodiment, the functionalized polyolefin (c) and monoamine terminated polyalkylene oxide (d) form an adduct that is thermo dynamically miscible with the copolymer (b) at adduct: copolymer (b) ratios of from 0.1:9.9 to 9.9:0.1.
