Abstract
Disclosed is a shaped article comprising a continuous oriented polymer matrix having dispersed therein microbeads of a polymer which are at least partially boredered by void space, the microbeads being present in an amount of about 5-50% by weight based on the weight of said oriented polymer, said void space occupying about 2-60% by volume of said shaped article. Preferably, the microbeads are cross-linked to an extent they will be resilient and elastic at the orientation temperature, and are coated with a slip agent. The shaped article is preferably in the form of a sheet, fibers, or other molded article, preferably has a relatively low specific gravity and whiteness.
