Abstract

Herein, we report the UV-induced controlled radical polymerization facilitated by titanium dioxide nanoparticles and trithiocarbonate derivatives, serving as photocatalysts and chain transfer agents, respectively. The polymerization proceeded through a reversible addition–fragmentation chain transfer (RAFT) process. The resulting polymers exhibited well-controlled molecular weights and relatively low polydispersity. Additionally, the chain extension reaction via UV-induced RAFT polymerization using titanium dioxide nanoparticles yielded higher-molecular weight polymer products.
通过 RAFT 工艺使用二氧化钛纳米粒子进行紫外线诱导的受控自由基聚合反应
在此,我们报告了分别作为光催化剂和链转移剂的二氧化钛纳米颗粒和三硫代碳酸酯衍生物促进紫外线诱导的受控自由基聚合。聚合是通过可逆的加成-断裂链转移(RAFT)过程进行的。所得到的聚合物分子量控制得很好,多分散性相对较低。此外,通过使用二氧化钛纳米粒子进行紫外线诱导的 RAFT 聚合反应,链延伸反应产生了更高分子量的聚合物产品。
