  • Patent number: 7652094
    Abstract: 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.

  • Patent number: 6114443
    Abstract: The present invention is based on the discovery that diblock copolymers of ethylene and an atactic alpha-olefin that are prepared in the presence of a catalyst system comprising at least one metallocene compound and a non-coordinating anion are especially useful as compatibilizers with blends of polyethylene and isotactic poly-alpha-olefin homopolymers.
