Abstract:
A polyolefin composition that comprises:(a) a polyolefin that comprises ethylene, wherein said polyolefin has a melt index from about 3 to about 10 grams per ten minutes as measured in accordance with ASTM D1238 (190/2.16), and a density greater than 0.938 grams per cubic centimeter as measured in accordance with ASTM 1505, and wherein said polyolefin that comprises ethylene is a homopolymer or a copolymer, where said copolymer comprises ethylene as the major component, as measured by mole percent, of said copolymer; and (b) dibenzylidene sorbitol, in an amount equal to, or greater than, the amount required to increase the notch izod impact strength of a composition that consists essentially of said polyolefin and said dibenzylidene sorbitol, by greater than 10 percent over the notched izod impact strength of a composition that consists essentially of said polyolefin, where said notch izod impact strengths are measured in accordance with ASTM D256-90b.
