Abstract

1285207 Moulding polydiene polyurethane articles TRW Inc 28 Oct 1969 [28 Feb 1969] 52842/69 Heading C3P A sheet is made from a mixture of the reaction product of a polyfunctional polydiene prepolymer having at least 50% of its olefinic unsaturation in the form of pendant vinyl groups on alternate carbon atoms of a backbone chain and a polyfunctional organic chain extender and a free-radical initiator, the sheet is placed in a forming die and the sheet is cured by the application of heat and pressure. The resins are further described in Specifications 1,193,301, 1,193,734, 1,194,723, 1,195,566 and 1,195,565. The initiator may be present in the initial mixture or added to the rubbery reaction product.
