  • Process for the preparation of a thermoplastic elastomer comprising a partially vulcanized rubber concentrate
    Patent number: 7572858
    Abstract: Process for the preparation of a thermoplastic elastomer by melt mixing a partially vulcanized rubber concentrate, a thermoplastic polymer and/or additives, optionally oil and a curing agent. The partially vulcanized rubber concentrate is prepared by melt mixing at least one elastomer and optionally oil with a thermoplastic polymer and a curing agent. The elastomer may be EPDM or EPM. The thermoplastic polymer may be chosen from a thermoplastic polyolefin. Useful curing agents are for example sulfur, sulfurous compounds, metal oxides, maleimides, phenol resins, siloxanes or peroxides.
