Title:
ETHYLENE COPOLYMER MODIFIED ORIENTED POLYPROPYLENE
Document Type and Number:
WIPO Patent Application WO2005087848
Kind Code:
A3
Abstract:
Disclosed are oriented films, tapes, and melt-spun fibers prepared from compositions comprising (a) at least one polypropylene polymer; and (b) 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 nonmodified polypropylene compositions. Also disclosed are woven, nonwoven and knitted textiles prepared from the oriented melt-spun fibers described, and methods for producing slit film fibers of the invention.
