摘要： A polypropylene composition and modified fibers thereof, includes polypropylene and an elastomer. The elastomer has a melting temperature of, at least, 80° C., preferably 100-180° C., a melt flow index in the range of 1-60 g/10-min., and a density within the range of 0.85-0.95 g/cm3. The elastomer is a branched copolymer of an ethylene copolymer, a polyolefin copolymer or a combination thereof, with ethylene, higher alkene groups, or both ethylene and higher alkene groups in the main chain of the branched copolymer, and with a weight proportion of polypropylene to elastomer being in the range of from 99.9:0.1 to 0.1:99.9. A method for producing the polypropylene composition and modified fibers thereof is also disclosed.
