大分子单体参与分散聚合制备功能性微球的研究

PREPARATION OF FUNCTIONAL MICROSPHERES BY DISPERSION POLYMERIZATION WITH MACROMONOMER

由于大分子单体具有特殊的结构和性质,它代替传统的稳定剂参与分散聚合,具有实验操作过程简便,制得微球表面洁净,粒径呈单分散性等优点。近年来,大分子单体已成为高分子科学研究的热点之一。文中对在分散聚合反应中采用大分子单体技术制备功能性微球的研究进行了综述。

Macromonomer usually contains a polymerizable group on one chain end, so that it can be copolymerized with a conventional monomer. In the dispersion polymerization, the functional microspheres can be prepared by macromonomer technique. During the polymerization, the macromonomer acts not only as stabilizer but also as comonomer, and the prepared functional microspheres have narrow size-distribution and their surfaces are very clean. In recent years, many functional microspheres have been prepared with macromonomers. The preparation of functional microspheres by dispersion polymerization with macromonomer was reviewed.
