Abstract

1299252 Vulcanized latices SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 11 May 1970 [12 May 1969] 22642/70 Heading C3P An aqueous dispersion of a cross-linked polyisoprene having at least 40% of its units in the cis-1,4 configuration is prepared by reacting an aqueous dispersion of the uncross-linked polyisoprene with a free radical-yielding compound at a temperature above 20‹ C. in the absence of a redox system and polymerizable material.
