Abstract

Disclosed are films, tapes, and melt-spun fibers prepared from a composition comprising (a) at least one polyester polymer and (b) from about 1 to 30 weight % of at least one ethylene copolymer such as ethylene/vinyl acetate dipolymers, ethylene/vinyl acetate terpolymers, ethylene/alkyl (meth)acrylate dipolymers, ethylene/alkyl (meth)acrylate terpolymers, functionalized ethylene copolymers, ethylene/acid copolymers, and salts thereof. The films, tapes and fibers exhibit improved tensile properties such as tensile strength and elongation at break compared to non-modified polyester compositions. Also disclosed are textiles and articles prepared from the fibers described.
