Abstract

A reinforced synthetic rubber latex has an average particle size in excess of 1,000 angstroms, the disperse phase of the latex being composed of spherical composite particles containing a synthetic conjugated diene rubber and a rubber reinforcing substance. Specified rubbers are polybutadiene, polyisoprene, polychloroprene, butadiene-acrylate, isobutylene-isoprene, butadiene-acrylonitrile chloreprene-nitrile, butadiene-pyridine, styrene-chloroprene and styrene-isoprene rubbers. The rubber reinforcing substance may be polystyrene, chlorinated styrene polymers styrene-acrylonitrile copolymers, vinyl or vinylidene polymers or copolymers, cross-linked styrene polymers, polymethylmethacrylate, cross-linked styrene-butadiene copolymers, hard vulcanised SBR and polybutadiene, styrene-butadiene-divinyl benzene-methacrylic acid quaternary polymers neutralized by an amine or alkaline substance, carbon black, rubber reinforcing silica, water soluble metal silicates and calcium carbonate. Vulcanizing ingredients may be introduced into the latex, the latex frothed, gelled and vulcanized. A pigment filler e.g. calcium carbonate or a phosphate may be added to the latex before foaming. Referring to Example (1) a butadiene-divinyl benzene-styrene terpolymer latex containing 10 parts terpolymer and a GR-S latex containing 100 parts rubber are agglomerated and concentrated and then mixed with sulphur, vulcanizing ingredients and antioxidant whipped to a foam with diphenyl guanidine, zinc oxide and sodium silicofluoride dispersions put on a heated mold, gelled and vulcanized. Examples (2) to (6) employ similar foaming techniques on different mixtures.
