1 more element
A controlled nucleated polymer comprising:
- (I) a polyolefin resin comprising:
- (i) from about 65% to about 95% by weight of a propylene homopolymer, or a copolymer selected from the group consisting of (a) propylene and ethylene, (b) propylene, ethylene and a C4-C8 α-olefin, and (c) propylene and a C4-C8 α-olefin, the copolymer having a propylene content of more than 85% by weight;
- and (ii) from about 5% to about 35% by weight of an elastomeric copolymer selected from the group consisting of (a) ethylene and propylene, (b) ethylene, propylene, and a C4-C8 α-olefin, and (c) ethylene and a C4-C8 α-olefin, the copolymer optionally containing about 0.5% to about 10% by weight of a diene;
- (II) sodium benzoate;
- and
- (III) an ionic stearate salt.
