Abstract: PURPOSE:To facilitate the imparting of a solid shape such as convex and concave with an improved compression molding property by a thermal compression molding of polyurethane foam containing a polymer of an ethylating insaturated monomer. CONSTITUTION:An ethylating insaturated monomer such as acrylonitrile and styrene is dissolved into polyol to disperse a thermoplastic polymer into the polyol by polymerization or to make a polymer polyol formed as a graft polymer. The matter thus obtained is blended with an additive such a polyisocyanate and foaming agent and hardened foaming. The content of the thermal plastic resin provides a favorable result at a lower temperature and in a shorter time than before because of excellence in the thermal compression molding property. A polymer of ethylating insaturated monomer may be dispersed or dissolved into the polyol beforehand. The molding thus obtained is ideal for the manufacture of cushion materials for vahicle and furniture or the like.

Abstract: PURPOSE:To mold a molded product excellent in heat resistance at low temp. within a short time, in laminating a facing material to synthetic resin foam, by preliminarily providing a layer containing luctams and an oxidation inhibitor between both of them. CONSTITUTION:A solution mixture of epsilon-caproluctam and an oxidation inhigiror (2,6-di-t-butyl-p-cresol) is applied to the surface of soft polyester urethane foam. Subsequently, nylon jersey base cloth is laminated to the coating layer as a surface side facing material and commpressed under heating to obtain a laminate. The luctam and the oxidation inhibitor in the coating layer are reacted and cured with the advance of thermal compression molding and the adhesiveness between the surfaces of the foam and the facing material is enhanced and a good embossing property is imparted. Therefore, the objective integral laminated molded product of the facing material and the foam having a sharp and acute embossed shape is easily obtained even at low compression temp. (140 deg.C) within a short compression time (5min).
