摘要

研究了5-乙烯基四唑在二苄基三硫代碳酸酯存在下的可逆链转移自由基聚合反应。采用核磁共振波谱法对聚合动力学进行了研究，得到了单体与二苄基三硫代碳酸酯转化的数据，并对聚合速率进行了分析。并与传统的5-乙烯基四唑自由基聚合动力学进行了比较

EFFECT OF DIBENZYLTRITHIOCARBONATE ON THE KINETICS OF 5-VINYLTETRAZOLE RADICAL POLYMERIZATION

Radical polymerization with reversible chain transfer by the addition-fragmentation mechanism of 5-vinyltetrazole in the presence of dibenzyltrithiocarbonate was carried out. The kinetics of the polymerization was studied by NMR spectroscopy: data on the conversion of the monomer and dibenzyltrithiocarbonate, and the rate of polymerization were obtained and analyzed. A comparison was made with the kinetics of the classical radical polymerization of 5-vinyltetrazole
