Abstract
The present invention describes polymer comprising one or more C3 to C40 olefins and having a Mw of 100,000 or less and a Dot T-Peel of 1 Newton or more. The polymer may have a branching index (g') of 0.95 or less measured at the Mz of the polymer, and a heat of fusion of 1 to 70 J/g. Also described are polymers of homopolypropylene or a copolymer of propylene and up to 5 mole % ethylene having: an isotactic run length of 1 to 30 as determined by Carbon 13 NMR and a percent of r dyad of greater than 20%, preferably from 20 to 70% as determined by Carbon 13 NMR. Also described are methods of making these and other polymers.
