Abstract

The invention belongs to the technical field of photo-initiation polymer polymerization and particularly relates to a silver halide based photoinitiator and application of the silver halide based photoinitiator to light-induction unsaturated olefin monomer polymerization. Active silver halide based material is used as a photoinitiator, and organic polymer material is prepared through induction polymerization under ultraviolet light. Firstly, surface active agent is added into halide salt water solution, then silver nitrate solution is added under a stirring condition to perform reaction, and the active silver halide based photoinitiator is obtained through dialysis, the silver halide based photoinitiator, the unsaturated olefin monomer and water are mixed to form stable dispersion liquid, active silver halide particles in the silver halide based photoinitiator absorb ultraviolet light to generate free radical under the irradiation of an ultraviolet lamp, unsaturated olefin monomer polymerization is initiated, and then the organic polymer material is prepared. The polymerization reaction can be carried out in water phase, the using range of suitable monomers and low polymers is wide, and the silver halide based photoinitiator has the characteristics of quick reaction speed, gentle reaction condition, environment protection and the like.

Description

technical field

[0001] The invention belongs to the technical field of photoinitiated polymer polymerization, and specifically relates to a silver halide-based photoinitiator and its application in light-induced polymerization of unsaturated olefin monomers. Active silver halide-based materials are used as the photoinitiator, Induced polymerization to prepare organic polymer materials. Background technique

[0002] Photoinitiator is a kind of material that can absorb light energy of a certain wavelength, generate active free radicals, trigger the double bond reaction in the system to form a growing chain, and initiate monomer polymerization, crosslinking and curing. Visible photoinitiators are limited in application because they are not sensitive to sunlight and general lighting sources. Therefore, most of the currently used photoinitiators are ultraviolet photoinitiators. According to the different active intermediates produced, it can be divided into free radical type and...
