以杨梅型聚羧酸铜/亚硫酸钠体系引发甲基丙烯酸甲酯水溶液聚合,测得表观聚合速率Rp=1.2×10~(14)e~(-21400/■)[MMA]~(1.3)[Na_2SO_3]~(0.5)[UP-Cu]~0,聚合按自由基机理进行。聚羧酸铜/亚硫酸钠/甲基丙烯酸甲酯之间通过“络合—氢转移”过程产生初级自由基。
The apparent polymerization rate Rp = 1.2 × 10 ~ (14) e ~ (-21400 / ■) [MMA] ~ (1.3) was obtained by the polymerization of methylmethacrylate with bayberry polycarboxylate / sodium sulfite system. Na_2SO_3] ~ (0.5) [UP-Cu] ~ 0, the polymerization proceeds according to the free radical mechanism. Polycarboxylate copper / sodium sulfite / methyl methacrylate by “complex - hydrogen transfer” process to generate primary free radicals.
