POLYMER BLENDS OF TRIMETHYLENE TEREPHTHALATE AND AN ELASTOMERIC POLYESTER

摘要

A polymer blend consisting essentially of at least 50% by weight, based on the total weight of the composition, of polytrimethylene terephthalate and a polyamide. Oriented fibers and extrusions produced from the polymer blend are durable under repetitive compressive stresses, exhibit mechanical properties comparable to neat polyamide-6, and provide moisture stability similar to yarns and extrusions comprised of polyamide-6/10 or polyamide-6/12.
