Abstract:
A composition comprising a blend of(1) a propylene polymer selected from the group consisting of (a) a propylene homopolymer and (b) a copolymer of propylene and ethylene or a 4-8 C alpha-olefin, wherein the content of polymerized ethylene or polymerized alpha-olefin is 10% or less, the propylene polymer having an isotactic index of greater than 90, and(2) a propylene polymer made with a metallocene catalyst and selected from the group consisting of (a) a propylene homopolymer and (b) a copolymer of propylene and ethylene or a 4-8 C alpha-olefin wherein the content of polymerized ethylene or polymerized alpha-olefin is 10% or less, the propylene polymer having a crystallinity of less than 24% measured from the heat of crystallization,the blend having a melt tension of greater than 7 centiNewtons at 200.degree. C. and a Young's modulus of less than 1000 MPa.
