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.
描述了钒基催化剂在烯烃的(共)聚合中的促进剂,特别是在乙烯/丙烯(EPR)或乙烯/丙烯/二烯(EPDM)弹性共聚物的生产中使用。本发明的促进剂属于具有一般化学式I的化合物组:其中:"X"代表一个(-CO-)羰基或(-SO2-)磺酰基;"n"为0或1;R'是具有1至20个碳原子的烷基或烷基芳基基团;R" = R', H。
