Abstract

Compositions of synthetic rubber, e.g. polychloroprene or polybutadiene, a copolymer of butadiene with isobutylene, styrene, methyl methacrylate or acrylonitrile, and of synthetic rubbers with which extender oils have been incorporated, are reinforced by incorporation of compounds having a cationic long chain radical attached to an anionic lignin residue. The rubber and reinforcing agent may be coprecipitated from an alkaline aqueous dispersion of the rubber containing a hydrophilic lignin compound, e.g. lignin itself or a lignin sulphonic acid, or an alkali or alkaline earth metal salt thereof, and an organic compound containing a cationic long chain radical, e.g. dodecyl, octadecyl or cetyl trimethyl ammonium bromide, p-tert.-octyl-m-methyl-phenoxyethoxy-ethyl dimethyl benzyl ammonium chloride or bromide, or N-cetyl, -dodecyl, -octadecyl or -stearyl pyridinium chloride. The compositions may be vulcanized.ALSO:Compounds having a cationic long-chain radical attached to an anionic lignin residue are employed for the reinforcement of rubber compositions. The reinforcing agent may be coprecipitated with rubber by the addition of acetic acid to an alkaline aqueous dispersion of rubber containing a hydrophilic lignin compound, e.g. lignin itself or a lignin sulphonic acid, or an alkali or alkaline earth metal salt thereof, and an organic compound containing a cationic long-chain radical, e.g. cetyl, dodecyl or octadecyl trimethyl ammonium bromide, p-tert.-octyl-m-methyl-phenoxy-ethoxy-ethyl dimethyl benzyl ammonium bromide or chloride, N-cetyl, -dodecyl, -octadecyl or -stearyl pyridinium chloride.ALSO:Rubber compositions are reinforced by incorporation of compounds having a cationic long chain radical attached to an anionic lignin residue. Rubber and the reinforcing agent may be coprecipitated from an alkaline aqueous dispersion of rubber containing a hydrophilic lignin compound, e.g. lignin itself or a lignin sulphonic acid, or an alkali or alkaline earth metal salt thereof, and an organic compound containing a cationic long chain radical, e.g. cetyl, dodecyl or octadecyl trimethyl ammonium bromide, p-tert.-octyl-m-methyl-phenoxy-ethoxy-ethyl dimethyl benzyl ammonium bromide or chloride, or N-cetyl, N-dodecyl, N-octadecyl or N-stearyl pyridinium chloride.
