This invention relates to a functionalized co-oligomer having an Mn of 300 to 30,000 g/mol comprising 10 to 90 mol% propylene and 10 to 90 mol% of ethylene, wherein the oligomer has at least X% allyl chain ends, where: 1) X = (-0.94 (mol% ethylene incorporated) + 100), when 10 to 60 mol% ethylene is present in the co-oligomer, and 2) X = 45, when greater than 60 and less than 70 mol% ethylene is present in the co-oligomer, and 3) X = (1.83* (mol% ethylene incorporated) -83), when 70 to 90 mol% ethylene is present in the co-oligomer. This invention also relates to a functionalized homo-oligomer, comprising propylene, wherein the oligomer has: at least 93% allyl chain ends, an Mn of about 500 to about 20,000 g/mol, an isobutyl chain end to allylic vinyl group ratio of 0.8: 1 to 1.2: 1.0, and less than 100 ppm aluminum. This invention also relates to a process of making functionalized homo-or co-oligomer, comprising propylene, wherein the productivity is greater than 4500 g/mmol Hf (or Zr)/hour. |
