ABSTRACT:
The present invention relates to plasticized polyolefin compositions comprising a polyolefin and a non-functionalized plasticizer; wherein the non-functionalized plasticizer may comprise C6to C200paraffins (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 C6to C25isoparaffins. In another embodiment the non-functionalized plasticizer is a polyalphaolefin comprising C10to C100n-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.
