Promoters are described for vanadium-based catalysts used in the (co)polymerization of olefins and, in particular, in the production of ethylene/propylene (EPR) or ethylene/propylene/diene (EPDM) elastomeric copolymers. The promoters of the present invention belong to the group of compounds having general formula I:
wherein:
"X" represents a (-CO-) carbonyl or (-SO2-) sulfonyl group;
"n" is 0 or 1;
R' is an alkyl or alkylaryl group having from 1 to 20 carbon atoms;
R" = R', H.
本发明描述了用于烯烃(共)聚合,特别是用于生产乙烯/丙烯(EPR)或乙烯/丙烯/二烯(EPDM)弹性共聚物的钒基催化剂的促进剂。本发明的促进剂属于具有通式 I 的化合物组:
其中
"X "代表(-CO-)羰基或(-SO2-)磺酰基;
"n "是 0 或 1;
R'是具有 1 至 20 个碳原子的烷基或烷基芳基;
R" = R',H。
