Abstract
A hot-melt adhesive composition comprising a styrene-type hydrocarbon-modified polyolefin (c) composed of 100 parts by weight of a crystalline polyolefin (a) having a degree of crystallinity of at least 10% and 0.15 to 50 parts by weight of a styrene-type hydrocarbon (b) bound thereto by great-copolymerization, said modified polyolefin (c) having an intrinsic viscosity [.eta.] of 0.5 to 5 dl/g, a degree of crystallinity of at least 10% and a weight average molecular weight Mw/number average molecular weight Mn ratio of from 1 to 15; and use of the aforesaid composition as an intermediate adhesive layer in laminating two polymers.
