摘要：

Hydrophilic (co)polymers carrying a thiocarbonyl thio end group such as poly(dimethylaminoethyl methacrylate), poly(ethylene oxide), and poly(ethylene oxide)-block-poly (dimethylaminoethyl methacrylate) have been evaluated as precursors of stabilizers merization of styrene under acidic conditions to form electrosterically stabilized polystyrene latex particles. As a mixture of P(DMAEA/H+Cl-)-RAFT and PEO-RAFT failed to give satisfactory results, PEO-RAFT was used as a control agent for the RAFT polymerization of DMAEMA, and the resulting block copolymer was successfully used in ab initio styrene emulsion polymerization.
