Claim:
1. A polyolefin composition comprising: A) from 65 to 85 wt. %, based upon the total weight of the polyolefin composition, of a propylene/ethylene/1-butene terpolymer wherein: B) from 15 to 35 wt % of a propylene/ethylene copolymer, based upon the total weight of the polyolefin composition, having a content of ethylene derived units ranging from 10.0 to 40.0 wt %; wherein the combined weight of the terpolymer and the copolymer equals 100 wt %, and wherein the tensile modulus of the polyolefin composition is greater than 480 MPa (ISO 527).
