原子转移自由基乳液聚合制备聚合物粒子

Polymer particles prepared by atom transfer radical emulsion polymerization

成功合成原子转移自由基用的引发剂,并采用原子转移自由基乳液聚合法,以此引发剂制备出聚合物粒子.用红外光谱(FT-IR)对引发剂及聚合物粒子的结构进行了表征,并采用光子相关光谱(PCS)、透射电子显微镜(TEM)和原子力显微镜(AFM)对聚合物粒子的形貌、粒径和粒径分布进行探究分析,结果表明:合成的聚合物粒子大小均一,小于100 nm,分散性较好.

An ATRP initiator was synthesized successfully, with which polymer particles were prepared by atom transfer radical emulsion polymerization. The structure of initiator and polymer particles were characterized polymer particles were chara by cte FT-IR spectrum. The morphology, size and size distribution of the rized by photon correlation microscopy （TEM） and atomic force microscopy （AFM）. spectroscopy / It was found （PCS）, transmission electron that the diameters of polymer particles were smaller than 100 nm and monodisperse.
