Reducing doped polyacetylene crosslinking and embrittlement and compositions containing polyacetylene so treated

摘要

A process for reducing doped polyacetylene crosslinking and embrittlement comprises treating the polyacetylene with one or more of the following agents:(a) hindered phenols;(b) alkyl ethers of hydroquinone, wherein the alkyl groups have 1 to 12 carbon atoms; and(c) dialkyl thiodipropionates wherein each alkyl group has 1 to 18 carbon atoms and the alkyl groups in a single compound may be the same as or different from each other; so as to distribute the agent(s) through the polyacetylene.;The polyacetylene must be doped before treatment which may be by simple immersion of the polyacetylene in pure protection agent, of a liquid, or a solution thereof. The treated polyacetylene has the protection agent(s) distributed therethrough.
