Abstract
A dynamically vulcanized composition comprising a polyolefin resin and an elastomer is provided in which a major portion of fillers or specified additives are present in the polyolefin resin. A process for producing the dynamically vulcanized composition is also provided including the addition of the fillers and/or specified additives after the dynamic vulcanization step. The compositions have improved stiffness to impact balance.
