Ultraviolet-induced controlled radical polymerization using titanium dioxide nanoparticles via the reversible addition-fragmentation chain transfer process.

Herein, we report the ultraviolet (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. [ABSTRACT FROM AUTHOR]
