Abstract

The invention relates to a photopolymerization initiating system, in particular to a free radical photopolymerization initiating system based on amino acid derivatives and a method for initiating free radical photopolymerization, belonging to the technical field of free radical polymerization. A free radical photopolymerization initiating system based on amino acid derivatives, based on the total weight of the water-soluble photopolymerization system as 100%, the free radical photopolymerization initiating system includes the following components in weight percentage: the first component: photosensitive agent, 0.01-1%; the second component: co-initiator, 0.25-1.25%, and the co-initiator is a nitrogen-terminal non-phenyl substituted carboxy-terminal blocked glycine derivative. The co-initiator of the present invention is a glycine derivative with non-phenyl-substituted carboxy-terminal closure at the nitrogen end, which is a colorless compound without chromophoric groups; the photoinitiating system has high tolerance to environmental alkali; The photoinitiation efficiency is excellent.

Description

technical field

[0001] The invention relates to a photopolymerization initiating system, in particular to a free radical photopolymerization initiating system based on amino acid derivatives and a method for initiating free radical photopolymerization, belonging to the technical field of free radical polymerization. Background technique

[0002] Photopolymerization (photocuring) is a process in which liquid monomers and / or oligomers undergo cross-linking and polymerization to form solid products under the irradiation of light (visible or ultraviolet light) or high-energy rays. It is energy-saving, environmentally friendly, and room temperature Polymerization, high polymerization speed, controllability of polymerization time and space, etc., is an environmentally friendly green production and processing technology. Since its invention in the 1960s, it has strongly promoted the progress of polymer science. It has a wide range of applications in the fields of medical repair, mi...
