Abstract: The present invention relates to a method for recovering raw materials (i.e. of polyols and optionally additionally amines) from polyurethane foams, comprising chemolysis. The chemolysis is characterised in that a polyurethane foam is reacted with an alcohol and water in the presence of a catalyst at a temperature of between 130° C. and 195° C., the mass ratio of (total) alcohol and (total) water to the polyurethane foam [i.e. m(alcohol+water)/m(polyurethane foam), where “m”=mass] being between 0.5 and 2.5, and the mass of the water being between 4.0% and 10% of the mass of the alcohol. The catalyst comprises a metal salt selected from a carbonate, a hydrogen carbonate, an orthophosphate, a monohydrogen orthophosphate, a metaphosphate or a mixture of two or more of said metal salts.

Abstract: Disclosed is an impact-resistant and aging-resistant reflective plastic applied to an automobile, which is prepared by copolymerizing of polyether polyol, 4,4,4-triphenylmethane triisocyanate and a benzimidazole derivative modified ZnS-mesoporous silica composite, the benzimidazole derivative modified ZnS-mesoporous silica composite is a ZnS-mesoporous silica composite modified by an anti-aging agent and a silane coupling agent KH-560, the ZnS-mesoporous silica is obtained by mixing an amphoteric surfactant, zinc chloride, and γ-aminopropyltrimethoxysilane uniformly, then reacting in ethyl orthosilicate, and calcining with hydrogen sulfide. In the present disclosure, by dispersing zinc sulfide in the pores of mesoporous carbon dioxide, chemical grafting 2-(2-hydroxy-5-aminophenyl)benzimidazole as a bridge onto isocyanate, and then polymerizing into polyurethane, which can improve the reflective performance and aging resistance of polyurethane, and improve the abrasion resistance and impact resistance.

Abstract: Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. In one embodiment, the outer cover layer is formed from a composition comprising a thermoplastic polyurethane and polydimethylsiloxane compound. Functionalized polydimethylsiloxane compounds also can be used to treat thermoplastic polyurethane golf ball covers. The cover composition and surface coatings can further include catalysts, ultraviolet (UV)—light stabilizers, and other additives. The coating methods have many benefits and the finished balls with thermoplastic polyurethane covers have good physical properties.
