Abstract:
1. An interpolymer of propylene, ethylene, and optionally, a diene, and wherein the interpolymer comprises 65 percent or more polymerized propylene, and wherein the interpolymer is made by a process comprising the following: copolymerizing propylene, ethylene, and optionally a diene, at a temperature from 100 to 130° C., a pressure from 100 KPa to 10 MPa, and a propylene/hydrogen flow ratio (g propylene/hr:g H wherein, X is an anionic ligand group; and covalent bonds are represented by lines and coordination interactions are represented by arrows; and wherein said interpolymer has a Mw from 50,000 to 150,000, a molecular weight distribution Mw/Mn from 2.0 to 10, a density from 0.860 to 0.885, an ethylene content from 5 to 15 weight percent, an isotacticity (percent mm) of at least 90, ΔH
