Abstract
A study was made of the radiation stability of vinylacetylene and its derivatives, namely, diethylaminomethylvinylacetylene, dipropargylaminomethylvinylacetylene, trimethylvinylethinylsilane and dimethylvinylethinylcarbinol. It was found that the main direction of radiation transformation of these compounds takes the form of polymerization reactions. The latter have two stages, the first featuring the formation of mainly soluble linear polymers, and the second resulting in the formation of insoluble space network polymers. On replacing the methine hydrogen in vinylacetylene by the relatively apolar trialkylsilyl and dialkylaminomethyl groups, a wider range of linear transformations is observed, while substitution of the hydrogen by the polar dimethylcarbonyl group extends the range of linear transformations, and leads to the formation of space network polymers.
