摘要

A series of random copolymers and block copolymers containing water-soluble 4AM and fluorescent VAK are synthesized by NMP. The homopolymerizations of 4AM and VAK and 4AM/VAK random copolymerization are performed in 50wt% DMF using 10 mol% SG1, resulting in a linear increase in ~M_n versus conversion, and final polymers with narrow molecular weight distributions (~M_w/~M_n < 1.4). Reactivity ratios r_(VAK) = 0.64 ±0.52 and r_(4AM) = 0.86 ± 0.66 are obtained for the 4AM/VAK random copolymerization. In addition, a poly(4AM) macroinitiator is used to initiate a surfactant-free suspension polymerization of VAK. After 2.5 h, the resulting amphiphilic block copolymer has M_n = 12.6 kg • mol~(-1), ~M_w/~M_n =1.48, molar composition F_(Vak) = 0.38 with latex particle sizes between 270 and 475 nm.
