甲基丙烯酸C7~C9酯的基闭转移聚合
Group Transfer Polymerization of C7~C9 Methacrylates
【摘要】 研究了甲基丙烯酸C7~C9酯的基团转移聚合。聚合必须在80℃以上进行,讨论了聚合条件对聚合速率、分子量、分散性及转化率的影响。
【Abstract】 Group transfer polymeriztion of C7 ~ C9 methacrylates was investigated by using 1-trimethyl-siloxy cyclohexene(TSCH) as initiator and tetrabutylammonium bibenzoate(TBABB)as cata-lyst.Polymer with higher molecular weighand low polydispersity was obtained.it is one kind of viscosityindex improver. GTP of the monomer must be carried out higher than 80℃。The depen-dences of the polymerkation rates,molecular weights and polydispersity,conversion on the polymerizationconditions also were studied.
