摘要：

Atom transfer radical polymerization of methyl methacrylate (MMA) was carried out by using perylene-copper coordination polymer network (Cu-PTC) with visible light activity as catalyst. The effect of catalyst/monomer ratio on the polymerization behavior of MMA was studied, and the polymerization conditions were optimized. The kinetic study shows that the polymerization process is consistent with the living radical polymerization characteristics. Moreover, the results of 1H-NMR show that the microporous structure of Cu-PTC can induce the photopolymerization of MMA and improve the stereoregularity of the polymer. UV-spectroscopy (UV), electron paramagnetic resonance spectroscopy (EPR) and electrochemical studies were carried out to investigate the mechanism of Cu-PTC as photoinduced catalyst for the polymerization of MMA. The results show that Cu-PTC is excited by photoexcitation to generate photogenerated electrons and holes. Photogenerated electrons activate an alpha-bromophenylacetate (EBP) initiator to achieve living polymerization. © 2020, Editorial Board of Polymer Materials Science & Engineering.
