摘　　要：基于可逆加成-断裂自由基聚合(RAFT),设计并合成了一种新型的梳状嵌段共聚物。通过凝胶渗透色谱仪(GPC)、核磁共振氢谱仪(^(1)R)、傅立叶变换红外光谱仪(FT-IR)等对共聚物进行了测试表征。将共聚物用于酞菁蓝颜料分散,利用马尔文激光粒径仪和旋转黏度计对其分散性能进行了测试,并与市售的某进口分散剂进行了对比。结果表明:所制备的梳状嵌段共聚物分散剂能使酞菁蓝颜料分散良好,色浆具有粒径小、黏度低、耐沉降、稳定性高的优异性能。A new comb block copolymer was designed and synthesized via reversible addition-fragmentation transfer(RAFT)polymerization.The copolymer was characterized by gel permeant chromatography(GPC),nuclear magnetic resonance hydrogen spectrum(^(1)H NMR)and Fourier infrared spectroscopy(FT-IR).Then the pigment slurry was prepared by the copolymer and phthalocyanine blue and its performance was studied using Malvin laser particle and rotating viscometer.The results showed that phthalocyanine blue can be well dispersed with small particle size,low viscosity,good settlement resistance and high stability.
