A general approach to degradable vinyl random copolymers via photocontrolled radical ring-opening cascade copolymerization (rROCCP) is developed. A variety of acrylates or acrylamides can be copolymerized with the macrocyclic allylic sulfone with near-unity comonomer reactivity ratios at all feed compositions. The unusual reversible inhibition of chain propagation by sulfur dioxide in rROCCP was resolved by reducing the solubility of sulfur dioxide.

光控自由基开环级联共聚可降解乙烯基无规共聚物**

开发了一种通过光控自由基开环级联共聚 (rROCCP) 制备可降解乙烯基无规共聚物的通用方法。各种丙烯酸酯或丙烯酰胺可以与大环烯丙基砜共聚，在所有进料组成中具有接近统一的共聚单体反应率。通过降低二氧化硫的溶解度来解决 rROCCP 中二氧化硫对链增长的异常可逆抑制。
