摘　　要：Using acetone-water as medium and 2,2′-azobisisobutyramidine dihydrochloride(AIBA) as cationic radical initiator, three emulsifier-free cationic copolymer nanoparticles were synthesized under microwave irradiation from styrene with methylmethacrylate, diacetoneacrylamide and β-hydroxyethyl-methacrylate respectively. The latexes were excellently stable. The particles were characterized by IR, TEM, LLS. The influence of comonomer content and hydrophilicity on the hydrodynamic radius <Rh> of copolymer nanoparticles was discussed. The results indicated that the average <Rh> of copolymer particle decreased with increase of the concentration and hydrophilicity of the comonomer.Using acetone-water as medium and 2,2′-azobisisobutyramidine dihydrochloride(AIBA) as cationic radical initiator, three emulsifier-free cationic copolymer nanoparticles were synthesized under microwave irradiation from styrene with methylmethacrylate, diacetoneacrylamide and β-hydroxyethyl-methacrylate respectively.
