A process to produce a polyolefin reactive telechelic pre-polymer comprising reacting alkyl-cis-cyclooctene, and optionally cis-cyclooctene, in the presence of a multifunctional chain transfer agent possessing two or more amino groups wherein the two or more amino groups are protected by one or more protecting groups under ring opening metathesis polymerization conditions to form a dicarbamate telechelic unsaturated polyolefin pre-polymer is provided.
本发明提供了一种生产聚烯烃活性远链预聚物的工艺,该工艺包括在具有两个或两个以上氨基的多功能链转移剂存在下,使烷基-顺式-环辛烯和任选的顺式-环辛烯发生反应,其中两个或两个以上氨基在开环偏析聚合条件下被一个或多个保护基团保护,以形成二氨基甲酸远链不饱和聚烯烃预聚物。
