ABSTRACT OF THE DISCLOSURE This invention provides an elastoplastic composition comprising a blend essentially free of low molecular weight phenol plasticizer of as thermoplastic crystalline polyamide in an amount sufficient to impart thermoplasticity up to 50 weight percent of the composition, wherein the polyamide in said blend retains at least 50% of its original crystallinity, b) rubber cross-linked to the extent that the gel content of the rubber is at least about 80 percent, wherein the rubber in said blend is in the form of small dispersed particles essenti- ally of the size of 50 microns or below and is a homopolymer of 1,3-butadiene, copolymer of 1,3-butadiene or isoprene or mix- tures thereo'. in an amount sufficient to impart rubberlike elasticity up to 80 weight percent of the composition provided that, when the amount of polyamide exceeds the amount of rubber, sufficient inert plasticiser is present to impart rubber- like elasticity to the composition which composition is process- able as a thermoplastic and is elastomeric. Elastoplastic com- positions of the invention are useful for making a variety of articles such as tires, hoses, belts, gaskets, moldings and molded parts . The compositions are useful for making articles by extrusion, injection molding and compression molding techni- ques and also for modifying thermoplastic resins.
