GROUP TRANSFER POLYMERIZATION OF LONG-CHAIN ALKYL METHACRYLATES
甲基丙烯酸长链烷基酯的基团转移聚合研究

Group transfer polymerization of C7-C9 methacrylates was investigated by using 1-trimethyl-siloxy cyclohexene (TSCH) as initiator and tetrabutylammonium bibenzoate (TBABB) as catalyst. Polymer with higher molecular weightand low polydispersity was obtained. It is one kind of viscosity index improver.GTPof the monomer must be carried out above 80t. The dependences of the polymerization rates, molecular weights and polydispersity, conversion on the polymerizationconditions had been investigated.
