Abstract

Cross-linked polyurethanes are produced by reacting (a) one or more saturated or unsaturated linear or branched chain hydroxy polyesters obtained by the reaction of one or more polyhydric alcohols with one or more saturated and/or unsaturated dicarboxylic acids with (b) organic polyisocyanates, in solution in one or more monovinyl and/or polyvinyl compounds which polymerize under the conditions of the reaction. The polyesters are obtained from acids such as oxalic, succinic, sebacic, phthalic, adipic, and maleic acids, and polyhydric alcohols such as butanediol, butenediol, butinediol, glycerol, trimethylol propane, triethanolamine, pentaerythritol, ethylene glycol, butylene glycol, diethylene glycol, methyldiethanolamine, hexanediol and octanediol; the polyesters may be modified by aminoalcohols, diamines, monoalcohols, or higher fatty acids, e.g. linseed oil acids; when polyesters made from maleic acid are used these copolymerize with the vinyl compounds. Polyisocyanates specified are hexamethylene-1,6-diisocyanate, 4,41 - dicyclohexyl - methane-diisocyanate, toluylenediisocyanate, polyisocyanates obtained by reacting polyhydroxy compounds, e.g. hexanetriol, with diisocyanates, and polyisocyanates obtained by reacting polyesters containing hydroxy groups, with an excess of diisocyanates as described in Specification 742,501. Vinyl compounds specified are styrene, esters of acrylic and methacrylic acids, e.g. methyl methacrylate, or mixtures thereof; the vinyl compounds may be used in the form of their liquid partial polymers. The reaction is accelerated by the application of heat, and the addition of tertiary amines such as diethylaniline, hexahydrodimethylaniline, and N,N - diethanol - p - biphenylamine, which may be used in conjunction with benzoyl peroxide. The reaction mixture may also contain inert substances such as carborundum, aluminium powder, sawdust, and glass wool. By carrying out the reaction in the presence of water or compounds containing carboxyl groups, e.g. carboxyl polyesters, carbon dioxide is evolved and a foamed product results. Textile fabric may be coated with the reaction mixture which is heated to produce a polymeric coating and layers of textile fabric may be laminated in this way. The process may also be applied to the production of mouldings, abrasive articles, and coatings generally.
