Abstract
PURPOSE: To obtain a firmly bonded multi-layer composite molded article, by bonding a polyolefin resin layer to an acrylic resin one with a specific intermediate layer laid between them.
CONSTITUTION: A) polyolefin resin, B) acrylic resin, and C) an intermediate layer resin consisting of a block copolymer shown by the formula IWIV (A is a polymer block substancially consisting of a monovinyl substituted aromatic compound; B is a polymer block substancially consisting of a conjugated diolefin; n is 1W10; X is a polyfunctional compound to which m polymer chains can be bonded; m is 3W7), having a molecular weight of 10,000W50,000 and conjugated diolefin content of 10W90 wt.% or its blend with polyolefin or acrylic resin or both are extruded from different extruders respectively and introduced in the same coextrusion multi-layer die. The polyolefin resin layer is bonded to the acrylic resin layer with the intermediate polymer layer put between them.
