Abstract

A method of obtaining sheets or filaments comprises forming a homogeneous blend comprising 10-80% by volume of a crystalline poly-(alpha-olefin) having a standard load melt index of substantially zero, the alpha-olefin having from 2-4 carbon atoms, 5-60% by volume of inert particulate filler material and 15-85% by volume of plasticizer, into a sheet or filament at a temperature above the coalescing temperature, and increasing the size of the sheet in at least one direction parallel to its surface or increasing the length of the filament, by at least 5% by stretching. The sheet or filament is preferably stretched at a temperature above the softening temperature of the blend. The usual fillers and plasticizers are used and these may be removed from the stretched sheet or filament by solvent extraction.
