  • Compositions for making films having improved mechanical properties and methods for making same
    Patent number: 8252861
    Abstract: Film tapes comprising a blend of a masterbatch and a propylene-based polymer are provided. The masterbatch comprises a propylene-based elastomer and filler. The propylene-based elastomer has about 50 to about 99 mol % of units derived from propylene, about 1 to about 50 mol % of units derived from C2-C20 comonomer and a peak melting point temperature of 115° C. or less. The propylene-based polymer comprises about 80 to about 100 mol % units derived from propylene and a peak melting point temperature of greater than 115° C. The compositions are suitable to make carpet fiber, carpet yarn, films, film tapes, molded parts and nonwoven fabrics having excellent mechanical properties.
