摘　　要：原子转移自由基聚合(ATRP)法克服了传统自由基聚合法的这种缺陷,因而合成的聚合物可具备更加优异的性能。含氟嵌段共聚物的疏水性能优于含氟无规共聚物,目前ATRP法制备的含氟嵌段共聚物大多采用单一丙烯酸酯类单体与含氟单体制备而成,其涂膜性能较差,本文通过ATRP法,利用两步聚合先制备P(MMA-HEMA-BA)-Br大分子引发剂,再利用该大分子引发剂引发含氟单体聚合生成P(MMA-HEMA-BA)-b-PFMA,最终合成的含氟嵌段共聚物分子量分布为1.21,这表明该聚合过程可控性好。ATRP is an excellent approach to avoid the defects of the conventional method,the polymers could obtain better performances. Fluorine- containing block copolymers possess has better hydrophobic performance than fluorined random copolymers. The fluorine- containing block copolymers prepared by ATRP is mostly applied by only one acrylic monomer and fluorine- containing monomer,the properties of the film are short for application. The fluorine- containing block copolymers was prepared by ATRP with two steps,firstly,the crosslinkable macroinitiator P（ MMA- HEMA- BA）- Br was prepared by ATRP. Then,the fluorine- containing block copolymer P（ MMA- HEMA- BA）- b- PFMA was prepared by ATRP with the P（ MMA- HEMA- BA）- Br as the initiator. The structures of the two copolymers were characterized by1 H NMR and GPC. The PDI of block polymerization was 1. 21. It included that the polymerization was in good control.
