Anionic Block Copolymerization of Methyl Methacrylate and C7~9 Methacrylate
Abstract:
The anionic block copolymerization of MMA and C7~9 methacrylate (C7~9 MA) was studied using n-BuLi as initiator. PC7~9 MA-b-PMMA copolymer was obtained. The influences of sequence in monomer-feed, temperature, concentration of initiator and active chain length of PC7~9 MA- on block copolymerization were discussed. When T=-20℃,[I]=(5.30±0.04)×10-2 mol/L and C7~9 MA as first monomer, PC7~9 MA- with Mn~1.6×104 was favorable to the copolymerization of PC7~9 MA-b-PMMA. The relative molecular mass and relative molecular mass distribution of copolymer were measured by GPC. The structure of block copolymer was characterized by FTIR and 1H NMR.
