ISOTACTIC POLYPROPYLENE PRODUCED FROM SUPERCRITICAL POLYMERIZATION PROCESS
Abstract:
This invention relates to an isotactic propylene homopolymer having: more than 15 and less than 100 regio defects (sum of 2,1-erythro and 2,1-threo insertions and 3,1-isomerizations ) per 10,000 propylene units; an Mw of 35000 g/mol or more; a peak melting temperature of greater than 149 0C; anmmmm pentad fraction of 0.85 or more; a heat of fusion of 80 J/g or more; and a peak melting temperature minus peak crystallization temperature (Tmp-Tcp) of less than or equal to (0.907 times Tmp) minus 99.64 (Tmp-Tcp
