Abstract

1335891 Polyurethane resins BAYER AG 7 July 1971 [11 July 1970] 31831/71 Heading C3R Polyurethane resins are shaped from aqueous' emulsifier-free latices prepared by dispensing a polyurethane mass in aqueous organic solvents and subsequent removal of solvent. The polyurethane is prepared from polyols of M.W. 350- 10,000, polyisocyanates, optionally chain extenders and alkali metal salts of addition products of cyclic aliphatic sultones and aliphatic diprimary amines, in which the above alkali metal salts are used in an amount such that 0À2-1À0% by wt. of SO 3 - groups are present in the dry polyurethane. The latices may be free from solvent and have a solid content > 40%. The resins may be vulcanized, e.g. by heating. Uses:-films, foils and coatings. Reference has been directed by the Comptroller to Specification 1,058,339.
