在ε-己内酯(CL)和丙烯酸丁酯(BA)单体共存的体系中,用预先合成的双键功能化烷氧基钛化合物和过氧化物作引发剂对CL和BA进行聚合。通过位于原位形成的以钛为中心的四臂聚己内酯末端的双键参与BA的自由基共聚合,形成了CL与BA交联的新型共聚物。采用多频流变法证实了共聚中交联凝胶的存在。
In systems where ε-caprolactone (CL) and butyl acrylate (BA) monomers coexist, CL and BA are polymerized using pre-synthesized double-bond functionalized titanium alkoxide compounds and peroxides as initiators. A new copolymer of CL and BA was formed through the radical copolymerization of BA with the double bond of the four-arm polycaprolactone end located in situ formed by titanium. Multi-frequency rheometry was used to confirm the existence of cross-linked gel in copolymerization.
