摘要：

The dehydrochlorination reaction that takes place during free-radical copolymerization of vinyl chloride with 1-vinylazoles was studied. It was shown that the degree of dehydrochlorination increases with the basicity of 1-vinylazoles. Relationships between the degree of dehydrochlorination and the composition of the initial mixture were determined. It was established that the hydrogen chloride being eliminated is completely trapped by the pyridine nitrogen atom of a heterocycle; thus, the autocatalytic character of the dehydrochlorination reaction is excluded.
