Abstract (en)
[origin: WO0001745A1] This invention relates to propylene-olefin (PO) copolymers having unique properties described herein as a relationship of mole % olefin to: 1) isotactic index, 2) % meso propylene triad, and 3) glass transition temperature. Specifically, the isotactic index of this invention's copolymers is equal to -0.0224O+A wherein O is the mole % olefin present, A is a number from 66 to 89, and the isotactic index is greater than 0. The propylene tacticity of this invention's polymers is also described by % meso triad equal to -0.4492O+B wherein O is the mole % olefin present, B is a number from 93 to 100, and the % meso triad is less than 95 %. Additionally, the copolymers of this invention have a glass transition temperature equal to -1.1082O-C wherein O is the mole % olefin present and C is a number from 1 to 14.
