The present disclosure provides a redox initiator system for initiating polymerization comprising an oxidizing agent, a photolabile reducing agent derived from a barbiturate, and a transition metal complex that participates in a redox cycle. On exposure to actinic radiation, such as UV, the photolabile compound photolyzes, releasing the reducing agent and initiating the redox-initiated polymerization.
本发明公开了一种用于引发聚合反应的氧化还原引发剂系统,包括氧化剂、源自巴比妥酸盐的光敏还原剂以及参与氧化还原循环的过渡金属配合物。在暴露于光化辐射(如紫外线)的情况下,光敏化合物发生光解,释放出还原剂并引发氧化还原引发的聚合反应。
