Silyl-terminated interpolymer of ethylene and method for preparing silyl- terminated polyolefins

摘要

There is disclosed a method for synthesizing polyolefins having a silyl group at one terminus, said method comprising reacting P P(A) a monomer selected from the group consisting of ethylene and a combination of ethylene and an -olefin; andP P(B) a silane having the formulaPPR.sup.2 R.sup.3 R.sup.4 SiH PP wherein R.sup.2, R.sup.3 and R.sup.4 each represents a monovalent group selected from the group consisting of hydrogen, alkyl having 1 to 4 carbon atoms, aryl, alkylaryl, arylalkyl, alkoxy having 1-4 carbon atoms, phenoxy, fluorinated alkyl having 3 to 6 carbon atoms, a dialkylamino group in which the alkyl groups contain 1 to 4 carbon atoms and a diorganopolysiloxane chain containing 1 to 10 siloxane units, said reaction taking place in the presence ofP P(C) a catalyst comprising a metallocene compound.
