通过半间歇CPDB介导的RAFT细乳液聚合技术合成了一系列聚合物链中具有广泛变化的单体单元的梯度含氟共聚物。在RAFT试剂2-氰基丙-2-基二硫代苯甲酸酯(CPDB)存在下,BMA和FMA的细乳液共聚表现出分子量可控、分散性窄的典型特征。对合成的含氟共聚物的大分子结构和热行为进行了详细的研究。差示扫描量热法(DSC)分析表明,该梯度共聚物具有独特的热行为,具有较宽的转变温度范围。研究还证实,含氟梯度共聚物具有明显的表面偏析结构和16.8 - 20.3 mN/m的超低表面能。© 2015 Wiley Periodicals,Inc. J.应用聚合物Sci.2016,133,42936.
A series of gradient fluorinated copolymers with a broad variation of the monomer units in the polymer chain were synthesized via semibatch CPDB‐mediated RAFT miniemulsion polymerization technique. In the presence of RAFT agent 2‐cyanoprop‐2‐yl dithiobenzoate (CPDB), the copolymerization of BMA and FMA in miniemulsion exhibited typical features of a controlled molecular weights and narrow polydispersities. The macromolecular structure and thermal behavior of the synthesized fluorinated copolymers were investigated in detail. The DSC analyses show that the gradient copolymers showed a unique thermal behavior with broad range of transition temperature. It was also confirmed that the fluorinated gradient copolymer exhibited obvious surface segregation structure and ultra‐low surface energy between 16.8 and 20.3 mN/m. © 2015 Wiley Periodicals, Inc.
