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.
A shaped article selected from the group comprising films, sheets, bottles, tubes, fibers and rods wherein said article comprises a continuous oriented polymer phase selected from the group comprising polyesters and polypropylene having dispersed therein microbeads of a cross-linked polymer coated with a slop agent and which are at least partially bordered by void space, said 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 wherein said cross-linked polymer comprises polymerizable organic material which is a member selected from the group consisting of an alkenyl aromatic compound having the general formula ##STR4## wherein Ar represents an aromatic hydrocarbon radical, or an aromatic halohydracarbon radical of the benzene series and R is hydrogen or the methyl radical;
A paper-like sheet comprising a continuous phase of oriented polyester having dispersed therein microbeads of crosslinked polymer coated with a slip agent which are encircled by void space when viewed in a direction perpendicular to the plane of the sheet,
A fiber or rod comprising a continuous phase of oriented polyester having dispersed therein microbeads comprising crosslinked polymer coated with a slop agent bounded on the lengthwise sides by void space
