The present invention is directed toward anionic polymerization employing lithio amines mixed with an organic alkali metal compound and optionally, a chelating reagent. The lithio amines have the general formula (A)Li(SOL)y, where SOL is a solubilizing component, A is an alkyl, dialkyl, cycloalkyl or dicycloalkyl amine radical or a cyclic amine, and y is 0 or is from about 0.5 to about 3. The invention is also directed toward polymers and other products made using the initiator, and methods therefor. Further, the invention contemplates a polymer, a polymer composition and products therefrom, which include a functional group from the reaction product of an amine and an organolithium compound. The resulting polymers may be terminated with a terminating, coupling or linking agent, which may provide the polymer with a multifunctionality.
本发明的目的是利用二元胺与有机碱金属化合物以及螯合试剂混合进行阴离子聚合。亚锂胺的通式为 (A)Li(SOL)y,其中 SOL 为增溶组分,A 为烷基、二烷基、环烷基或二环烷基胺基或环胺,y 为 0 或约 0.5 至约 3。本发明还涉及使用引发剂制造的聚合物和其他产品及其方法。此外,本发明还考虑了一种聚合物、聚合物组合物及其产品,其中包括来自胺和有机锂化合物反应产物的官能团。得到的聚合物可以用终止剂、偶联剂或连接剂终止,从而使聚合物具有多功能性。
