POLYMER COMPOSITIONS AND NONWOVEN MATERIALS PREPARED THEREFROM
摘要
The invention relates to a fiber comprising a blend of 10-50 wt% of a polymer blend modifier and 50-90 wt% of a propylene-based elastomer; 5-50 wt% of a propylene-modifier and 50-95 wt% of a propylene-based elastomer; and 5-35 wt% of a polymer blend modifier and 65-95 wt% of a propylene-modifier. The polymer blend modifier has a first propylene-based polymer and a different second propylene-based polymer that is a propylene homopolymer or a copolymer of propylene and ethylene and a C4 to C10 alpha-olefin. The propylene-modifier is a propylene homopolymer or a copolymer of propylene with 0.5-4 wt% ethylene or C4 to C10 alpha-olefins. The propylene-based elastomer is propylene and 5-25 wt% of one or more C2 to C4-C12 alpha-olefins and has a triad tacticity greater than 90% and a heat of fusion less than 75 J/g.
