Abstract
A flexible, homogeneous rubbery product comprising a matrix of a rubber selected from the group consisting of natural and synthetic elastomer in which there is uniformly dispersed at least 5% by weight based on the weight of the elastomer of a crystalline polyolefin whose molecular weight is equal to or greater than 500,000. A substantial proportion of the polyolefin is in the condition or form of fine particles which are drawn out in the form of elongated fibrils having a diameter smaller than 5 microns. This product exhibits a very high resistance to elongation in at least one direction.
