| titleOfInvention | Process for the production of thermoplastic urethane resins |
| abstract | A method for the production of synthetic resins by heating isocyanates with products containing alcohol groups, characterized in that an aromatic or aliphatic isocyanate is heated at 100-160 ° C with a product of general formula 1, in which R represents a phenyl group, a phenyl group substituted by one or two linear or branched alkyl groups and containing 1-9 carbon atoms, or one or two phenyl or cumyl groups and or 1-5 amino and chlorine atoms or bromine or represents a - naphthyl or ß-naphthyl group and is 1-4, possibly in the presence of a catalyst, in particular a tertiary amine or an organic tin, cobalt, lead or mercury compound, where as for products of general formula 1, in which R and n are as defined above, the addition products of phenol, cresols, xylenols, p-tert-butylphenol, p-hexylphenol, p-nonylphenol, ortho- and para-phenylphenol, p-cumylphenol, p-chlorophenol are most preferably used , trichlorophenols, pentachlorophenol, pentachlorophenol and alpha and beta naphthol to malmolecular dian epoxy resin, obtained with a molar ratio of phenolic compound to epoxy groups of 0.8-1.0.
