摘要 <p>1,235,816. Coating polyurethane foams. GENERAL TIRE &amp; RUBBER CO. 27 Oct., 1969 [12 Dec., 1968], No. 52481/69. Heading B2E. [Also in Division C3] A non-rigid polyurethane foam having an integral skin may have the skin coated with an abrasion resistant coating composition which comprises a chlorosulphonated polyethylene or polyurethane. The polyurethane foam is the reaction product in the presence of an organic blowing agent, of (a) an organic polyisocyanate, (b) a polyhydroxy containing graft polymer of an ethylenically unsaturated monomer on a backbone polymer of a polyether and/or polyester polyol and (c) an aryl diamine of particular formulae (see Division C3). The coatings are usually pigmented and deposited from a solution in an organic solvent. The foam coated with a chlorosulphonated polyethylene may have a top coating of a vinylchloride-vinylacetate copolymer.</p>
