Abstract
1526482 Vulcanizing liquid diene polymers MICHELIN ET CIE 29 Jan 1976 [30 Jan 1975] 03578/76 Heading C3P Liquid diene prepolymers having a degree of functionality of 1À8-2À0 are vulcanized by (1) forming a mixture thereof with reinforcing filler, a sulphur vulcanization agent and a difunctional chain extender compound in amount such that the ratio of functional groups on the polymer to those on the chain extender is 1, (2) subjecting the mixture to a temperature at which chain extension occurs exclusively, e.g. 20-125 C., and (3) subjecting the product to a higher temperature, e.g. above 140 C., to effect vulcanization. In Examples, hydroxyfunctional liquid butadiene/styrene copolymers are mixed with carbon black, a conventional sulphur-curing system and methylene diphenyl diisocyanate, and heated first to 110 C. and then to 155 C. or 160 C.
