ABSTRACT:
Disclosed is a soft and flexible thermoplastic resinous composition having high impact and tear resistances, a good processability and a good thermal adhesion to a wide variety of plastic and other materials. The resinous composition consists essentially of 5 to 70 wt. % of a thermoplastic polyurethane elastomer and 30 to 95 wt. % of a modified polyolefin or an olefin copolymer, having functional groups of at least one type selected from carboxyl, carboxylate salt, carboxylic anhydride, amide, hydroxyl and epoxy groups. A typical application of the thermoplastic resious composition is a laminate having at least two laminae bonded to each other, at least one of the laminae being comprised of the above-mentioned resinous composition and the other being comprised of at least one material selected from vinyl chloride polymer resins, vinylidene chloride polymer resins, thermoplastic polyester resins, ethylene/vinyl alcohol copolymer resins, polyamide resins, polyacrylonitrile and nitrile copolymer resins, polystyrene and styrene copolymer resins, polymethyl methacrylate and acrylic copolymer resins, polyurethane resins, olefin polymer resins, polyacetal resins, polyvinyl acetal resins, polycarbonate resins, polyphenylene oxide resins, polysulfone resins, epoxy resins, phenol-formaldehyde resins, unsaturated polyester resins, melamine-formaldehyde resins, urea-formaldehyde resins, natural and synthetic rubbers, cellulosic materials, cement, glass and other ceramic materials and metals.
