  • Bonding of rubber particles
    Patent number: 6565918
    Abstract: A coherent rubber composition is produced by: (a) coating the rubber particles with a polymeric unsaturated hydrocarbon compound; (b) mixing the resulting coated rubber particles with a bonding material; and (c) allowing and/or causing the resulting mixture to form the desired coherent rubber composition. The polymeric unsaturated hydrocarbon compound is conveniently a compound having a long chain aliphatic structure, for example a hydroxyl-substituted polymer of 1,3-butadiene. The bonding material is conveniently a pre-polymer for a polyurethane or polyurea, having terminal —NCO groups. Coherent rubber compositions obtained by the method are well suited for use as play surfaces or sports surfaces.
