This invention relates to a 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(mole % ethylene incorporated)+100), when 10 to 60 mole % ethylene is present in the co-oligomer, and 2) X=45, when greater than 60 and less than 70 mole % ethylene is present in the co-oligomer, and 3) X=(1.83*(mole % ethylene incorporated)−83), when 70 to 90 mole % ethylene is present in the co-oligomer. This invention also relates to a 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 homo-oligomer, comprising propylene, wherein the productivity is greater than 4500 g/mmol Hf (or Zr)/hour.
                            这项发明涉及一种共寡聚物,其Mn为300至30,000克/摩尔,包括10至90摩尔%的
丙烯和10至90摩尔%的
乙烯,其中寡聚物至少具有X%的烯丙基链端,其中:1)当共寡聚物中存在10至60摩尔%的
乙烯时,X=(-0.94(摩尔%
乙烯掺入)+100),2)当共寡聚物中存在60至70摩尔%的
乙烯时,X=45,3)当共寡聚物中存在70至90摩尔%的
乙烯时,X=(1.83*(摩尔%乙烃掺入)-83)。这项发明还涉及一种同源寡聚物,包括
丙烯,其中寡聚物具有:至少93%的烯丙基链端,约500至约20,000克/摩尔的Mn,异丁基链端到烯丙基
乙烯基比为0.8:1至1.2:1.0,以及少于100ppm的铝。这项发明还涉及一种制备同源寡聚物的方法,包括
丙烯,其中生产率大于4500克/毫摩尔Hf(或Zr)/小时。
