The addition of the swelling agent ( styrene) during the oxidative polymerization of DMP can increase the molecular weight of PPO due to the increase of the mobility of the oligomer chains in the polymer particle and the facilitation of the oxidative polymerization at the later period. DMP氧化聚合过程中引入溶胀剂苯乙烯,可提高PPO的相对分子质量,这是由于苯乙烯的引入能增加聚合物粒子相内预聚物分子链的活动性,促进聚合物粒子相内的后氧化聚合。
The chemical oxidative polymerization is adopted to prepare electrically-conductive fibers. Polyaniline, a novel conducting polymer, is synthesized on the surface of nylon 6 in air phase. 采用化学氧化聚合方法,在气相中将nylon6纤维表面合成一层导电高分子-聚笨胺。
The thermal oxidative degradation of the polymer alloy and the nanocomposites was studied by thermogravimetric analysis ( TG). 用热重分析法(TGA)研究了聚合物合金和纳米复合材料的热氧化降解行为。
