Abstract

1,185,418. Coated sheet materials. KALLE A.G. 9 Oct., 1968 [10 Oct., 1967], No. 47858/68. Heading B2E. [Also in Division C3] Sheet materials are coated with a polyurethane solution prepared by: (a) first reacting an excess of polyisocyanate with at least one polyester or polyether polyester obtained by reacting an aliphatic dicarboxylic acid with: in which R is H, Me, Et; y and z are each 1 or 2 and n is 0 to 12; (b) reacting the resultant NCO-terminated prepolymer with a chain extending low M.W. active hydrogen containing compound, optionally in a solvent, and adding solvent or more solvent during polyaddition step (b) until a predetermined viscosity is obtained (see Division C3). In an example a fleece of synthetic fibres (bound with butadiene acrylonitrile copolymer) is coated with a solution obtained by reacting an adipic acid/ dibutylene glycol polyester milk excess diphenylmethane-4, 4'-diisocyanate followed by chain extension with water in solution in dimethylformamide. The resultant coated structure is microporous.
