摘　　要：采用可逆加成裂解链转移自由基聚合法(RAFT),以四羟基卟啉为核制备RAFT链转移剂,以N-异丙基丙烯酰胺为单体合成四臂星形聚(N-异丙基丙烯酰胺)。通过红外光谱仪、核磁共振氢谱仪对聚合物的结构进行表征,结果表明,已成功地合成出星形聚(N-异丙基丙烯酰胺)。同时,聚合物的相对分子质量随反应时间的延长和单体浓度的增大而不断增长,呈现出“活性-可控”聚合特征。Four-arm star poly(N-isopropyl)Acrylamide)was prepared using the reversible addition cleavage chain transfer radical polymerization(RAFT)method,using the tetrahydroxyporphyrin core as the RAFT chain transfer agent.The structure of polymers were characterized by the infrared spectroscopy(FTIR),Hydrogen nuclear magnetic resonance spectrometer(1H-NMR),which showed that the star poly(N-isopropylacrylamide)has been synthesized successfully.Meanwhile the he molecular weight of the polymer showed a trend of increases variation with the increases change of reaction time and monomer concentration.The characteristics of"active controllable"polymerization are presented.
