Coextruded laminate

Abstract

A laminate having improved adhesion between sheets comprises at least one sheet of a first sheet composed of a high monoalkenyl arene content polymer and at least one sheet of a second sheet composed of block copolymers of monoalkenyl arenes and conjugated dienes, said block copolymer containing about 0.1 to about 10 percent by weight of a fatty acid amide, said first and second sheets being formed by coextrusion. In a preferred embodiment, the high monoalkenyl arene content polymer is polystyrene, the block copolymer is a styrene-butadiene copolymer, and the fatty acid amide is ethylene bis stearylamide.
