Problems solved by technology

Free radical photopolymerization has some serious disadvantages: firstly, free radical photopolymerization is severely inhibited by oxygen, and it is easy to cause poor surface curing, and it is often cured under an inert atmosphere, which is inconvenient to operate; large volume shrinkage
However, the cationic polymerization system also has its own shortcomings, such as being greatly affected by moisture, slow polymerization speed, and difficult to adjust performance, etc.

Abstract

The invention relates to the design and synthesis of a silicon-containing polymerizing monomer terminated by vinyl ether and allyl ether, which is prepared by using chlorosilane or chloro siloxane, hydroxyalkyl ethenyl ether and hydroxyalkyl allyl ether as raw materials. The reaction synthesis method is simple, the reaction conditions are mild, the purification is easy, and the yield is as high as over 80 percent. The synthesized monomer is a mixed polymerizing photocurable monomer and a novel photopolymerizing material which can be used for making an imaging information recording material. In the invention, the problems of complex preparation process, low yield, high cost, environment pollution and the like of the conventional silicon-containing photopolymerizing monomer are solved effectively, and a novel monomer is developed for making photocurable materials and photoimaging information recording materials.

Description

technical field [0001] The invention belongs to the technical field of preparation of optical functional materials for imaging information recording, in particular to a method for synthesizing silicon-containing polymerizable monomers whose end groups are vinyl ether and allyl ether. Background technique [0002] The so-called photoradical-cation hybrid curing system refers to a system in which two active species of free radicals and cationics occur simultaneously in the same system, thereby simultaneously generating free radical photopolymerization and cationic photopolymerization (Chen Qidao, Chen Ming, Hong Xiaoyin. Mixed Polymerization [J]. Chemical Bulletin. 2000, (6): 1-5; Chen Ming, Chen Qidao, Xiao Shanqiang, Hong Xiaoyin. The principle and application of hybrid photocuring system [J]. Photosensitive Science and Photochemistry. 2001, 19(3) : 208-216.). Free radical photopolymerization has some serious disadvantages: firstly, free radical photopolymerization is sever...
