在乳聚反应中,为使聚合物能具有优良的物理机械性能和加工工艺性能,就必须对分子量及其分布进行适当的调节和控制。采用的方法,主要是在乳聚过程中加入链转移剂或调节剂,以改变聚合物的链增长反应。 1937年,Flory首先提出了聚合反应中存在链转移剂的论点,并以下式予以描 In the emulsion polymerization, in order to make the polymer have excellent physical and mechanical properties and process performance, the molecular weight and its distribution must be properly adjusted and controlled. The method used is to add a chain transfer agent or regulator during the milk polymerization to change the chain growth reaction of the polymer. In 1937, Flory first proposed the argument that there was a chain transfer agent in the polymerization reaction and was described by
