Abstract
Polystyrene macrocycles have been prepared from ATRP precursors by modification of the terminal bromide to an azide, followed by "click" cyclization with a pendant alkyne from the initiator. This route offers exceptional control over the size and polydispersity of the macrocyclic polymers, as well as providing tolerance to a number of functional groups.
摘要
聚苯乙烯大环化合物是由原子转移自由基聚合（ATRP）前体通过将末端溴化物修饰为叠氮化物，然后与引发剂上的侧链炔烃进行“点击”环化反应制备而成。该方法能够对大环聚合物的尺寸和多分散性进行出色的控制，并且对多种官能团具有耐受性。
