Abstract
1,244,286. Polyurethane elastomers. ALLIED CHEMICAL CORP. 16 Dec., 1969 [28 Jan., 1969], No. 61355/69. Heading C3R. Polyurethane elastomers are prepared from a solvent-free composition comprising 4,4<SP>1</SP>- methylene dianiline and an isocyanate terminated prepolymer derived from 4,4<SP>1</SP>-methylenebis(cyclohexylisocyanate) and a polyol having a M.W. of 350 to 5000. The polyol is most suitably a polyalkylene ether polyol or a polyester polyol. In forming the prepolymer the NCO : OH ratio is preferably 1À4 : 1 to 3À0 : 1. Sufficient methylene dianiline should be added to react with 75 to 100% of the free isocyanate groups in the prepolymer.
