Description

technical field

[0001] The invention relates to the field of organic photocatalyst catalyzed controllable active free radical polymerization, in particular to the use of 1,1'-bi-2,2'-naphthol (BINOL, binaphthol) derivatives as methacrylate monomers Organic photocatalyst, an organic catalytic system that undergoes active controllable radical photopolymerization under visible light. Background technique

[0002] Since Szwarc et al. proposed the concept of living polymerization in 1956, living polymerization has become the most effective polymer synthesis method, because it can prepare polymers with specific structures and properties through precise design of polymer molecules, and truly realize precise control of molecular weight and molecular structure. Controlled / living radical polymerization (CRP) has the characteristics of relatively mild reaction conditions, wide range of applicable monomers, simple operation, low industrial cost, and wide application range of products, ...
