A novel route for the synthesis of poly(ethylene glycol)-b-polystyrene copolymer, starting from commercially available poly(ethylene glycol) methyl ether and azido terminated polystyrene prepared by atom transfer radical polymerization and subsequent nucleophilic substitution, is applied with simplicity and high efficiency. The combination of photoinduced copper (I)-catalyzed alkyne-azide cycloaddition (CuAAC) and ketene chemistry reactions proceeds either simultaneously or sequentially in a one-pot procedure under near-visible light irradiation. In both cases, excellent block copolymer formations are achieved, with an average molecular weight of around 7000 g mo1(-1) and a polydispersity index of 1.20.
一种合成聚（乙二醇）-b-聚苯乙烯共聚物的新途径，该途径从市售的聚（乙二醇）甲醚和通过原子转移自由基聚合及随后的亲核取代制备的叠氮基封端的聚苯乙烯开始，具有简单高效的特点。光诱导的铜（I）催化的炔烃-叠氮环加成（CuAAC）和乙烯酮化学反应在近可见光照射下以一锅法同时或顺序进行。在这两种情况下，均能实现优异的嵌段共聚物形成，平均分子量约为7000 g mo1(-1)，多分散指数为1.20。
