Abstract
A co-extruded polyolefin laminate having a hard, high modulus top layer includes at least one layer of a graft copolymer made from a propylene polymer material onto which is graft polymerized acrylic and/or styrenic monomers and at least one other layer made from a propylene homopolymer, a random propylene copolymer, a random propylene terpolymer, an olefin polymer composition, a thermoplastic olefin, a heterophasic olefin composition, or combinations of two or more of these polymers or polymer compositions, optionally blended with a high melt strength propylene polymer material. Composite materials including at least one layer of the co-extruded laminate and, for example, a low density polyolefin foam layer, can be used to make large structural parts by conventional means such as thermoforming.
