  • Patent number: 7645835
    Abstract: Blend compositions containing a novel homopolymer, the use of which allows the incorporation of more comonomer in the additional components of the blend (for the same overall density) resulting in increased tie molecule formation and improvement in properties such as ESCR, toughness and impact strength are disclosed. The homopolymers are important for applications where a high density is needed to ensure certain mechanical properties like abrasion resistance, indentation resistance, pressure resistance, topload resistance, modulus of elasticity, or morphology (for the chlorination of PE to CPE) and additional advantages such as melt processability. The blend can be obtained by dry or melt mixing the already produced components, or through in-situ production by in parallel and/or in series arranged reactors. These resins can be used in applications such as films, blow molded, injection molded, and rotomolded articles, fibers, and cable and wire coatings and jacketings and, various forms of pipe.

The nonwoven materials comprise fibers made from of a polymer blend of isotactic polypropylene and reactor grade propylene based elastomers or plastomers together with from about 100 to about 2500 ppm (by weight of the fiber) of a slip agent. The isotactic polypropylene can be homopolymer polypropylene, and/or random copolymers of propylene and one or more alpha-olefins. The reactor grade propylene based elastomers or plastomers have a molecular weight distribution of less than about 3.5, and a heat of fusion less than about 90 joules/gm. In particular, the reactor grade propylene based elastomers or plastomers contains from about 3 to about 15 percent by weight of units derived from an ethylene and a melt flow rate of from about 2 to about 200 grams/10 minutes. Erucamide is the preferred slip additive.
