摘要

研究了以非那嗪染料(中性红和红花红Т)为基础的催化体系在可见光照射下聚合甲基丙烯酸甲酯和其他(甲基)丙烯酸酯单体的特点。结果表明，不同结构的胺以及空气中的氧都会影响聚合的动力学特性和聚合物的分子量特性。研究发现，在室温和低光催化剂浓度下，聚合可以在控制模式下进行，达到高转化率，其中不需要对反应介质进行初步脱气。

Neutral Red and Safranin Т in the Photopolymerization of Methyl Methacrylate and Other (Meth)Acrylate Monomers

Features of the polymerization of methyl methacrylate and a number of other (meth)acrylate monomers in the presence of catalytic systems based on phenazine dyes (Neutral Red and Safranin Т) under visible light irradiation are investigated. It is shown that amines of various structure as well as air oxygen affect the kinetic features of polymerization and the molecular weight characteristics of polymers. It is found that polymerization may proceed in the controlled mode up to high conversions at room temperature and a low photocatalyst concentration, among them without preliminary degassing of the reaction medium.
