RUBBER-THERMOPLASTIC COMPOSITIONS .7. CHLORINATED POLYETHYLENE RUBBER-NYLON COMPOSITIONS

Data are presented which show that nylon resins and CPE rubber can be melt-blended to give compositions which have useful properties. If the rubber is cured by dynamic vulcanization high strength oil resistant thermoplastic elastomers result. Cold milling of melt-mixed compositions results in nylon-reinforced rubber which can be mixed with curatives and press cured or statically vulcanized to give reinforced rubber compositions which resemble vulcanized rubber-short fiber composites. The reason for the high integrity of either the statically or the dynamically vulcanized composition appears to be that chemical bonds form between the rubber and plastic.
