ABSTRACT:
Our invention is directed to a process for producing processable thermoplastic elastomer blends of nitrile rubber with a crystalline polyamide mixture of at least two polyamides at a temperature below the melting temperature of the highest melting polyamide, but above the melting point of the lowest melting polyamide. The amount of nitrile rubber ranges from about 20 to about 80 percent by weight with the polyamides ranging from about 80 to about 20 percent by weight. Although processed at a temperature below the melting point of the highest melting polyamide, usually present in a substantial amount, the compounds surprisingly were readily mixed with the blends being smooth with no loose or fibrous material therein.
