Abstract

DC60 (29/03/44) Multilayer plate made of olefin material. Polymers are (1) one or more outer layers of (a) polypropylene polymer, (b) graft copolymer made up of backbones of A polypropylene polymer material which is grafted polymerized to vinyl monomer, (a) or (b) that may choose to contain a nucleus. Or (c) an olefin polymer mixture and (2) one or more layers made of layers that Choice of polypropylene, polymer and glass fiber materials Multilayer plates made from olefin material Polymers include (1) Outer layer at least one layer of (a) polypropylene polymer, (b) graft copolymer made up of a polypropylene backbone. The polymer is grafted onto a vinyl monomer, (a) or (b) that may choose to contain a nucleus or (c) substance. Mix at least one layer of olefin polymer and (2) layers made from the Choice of polypropylene, polymer and glass fiber materials

Claims (1)

1. A multilayer sheet consisting of: (1) At least one outer layer composed of a polypropylene polymer material selected from Group containing: (a) propylene homopolymer or copolymer of propylene and ethylene, or 4-8 C alpha-olefin. The ethylene teeth that were polymerized. Or the polymerized alpha-olefin content of the copolymer is not more than 20% and may choose to contain a Approximately 0.15% to approximately 0.70% nucleus (b) A graph copolymer composed of backbones of polypropylene material.
