摘要：

Reversible addition fragmentation chain transfer (RAFT) ab initio emulsion polymerization of styrene using poly(acrylic acid)-b-polystyrene trithiocarbonate (AA(x)-b-St(y) macroRAFT) as both mediator and surfactant was investigated with systematically changed y from 0 to 7 and x from 15 to 30. A well-controlled polymerization in terms of little coagulum, well predicted molecular weight and low polydispersity (PDI) (approximate to 1.2) could only be achieved by using the macroRAFTs of hydrophile-lipophile balance (HLB) values between 13 and 20. The final latex particle size could be tuned from 80 to 172 nm in diameter simply by changing x and y values while the molecular weight was targeted the same (30 K).
