    摘要： The invention described relates to a polyolefin blend composition suitable for spunbond fiber or filament compositions, and to fabric compositions and composite constructions therefrom, said blend comprising a) from 60-98 wt % of at least one random propylene copolymer having a comonomer content of from 8 to 25 wt % and a crystalline melting point (Tm) as determined by differential scanning calorimetry (DSC) of from about 40° C. to about 110° C.; and b) from 2-40 wt % of at least one substantially isotactic polypropylene homopolymer or copolymer comprising one or more C2 and/or C4-C8 comonomer, having a crystalline melting point (Tm) as determined by DSC greater than or equal to 120° C. The blends of the present invention typically have a melt flow rate (MFR) of from 100 g/10 min to about 500 g/10 min.

    摘要： The present invention relates to plasticized polyolefin compositions comprising a polyolefin and a non-functionalized plasticizer; wherein the non-functionalized plasticizer may comprise C6 to C200 paraffins (including branched and normal paraffins) having a pour point of less than −5° C. In one embodiment, the non-functionalized plasticizer is an isoparaffin comprising C6 to C25 isoparaffins. In another embodiment the non-functionalized plasticizer is a polyalphaolefin comprising C10 to C100 n-paraffins. The polyolefin may be a polypropylene homopolymer, copolymer, impact copolymer, or blends thereof, and may include a plastomer. Non-limiting examples of desirable article of manufacture made from compositions of the invention include films, tubes, pipes, sheets, fibers, woven and nonwoven fabrics, automotive components, furniture, sporting equipment, food storage containers, transparent and semi-transparent articles, toys, tubing and pipes, and medical devices.
