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.
减少掺杂聚乙炔交联和脆化的工艺包括用以下一种或多种药剂处理聚乙炔:
(a) 受阻酚
(b) 对苯二酚的烷基醚,其中烷基具有 1 至 12 个碳原子;以及
(c) 二烷基硫代二丙酸酯,其中每个烷基有 1 至 18 个碳原子,单个化合物中的烷基可 以彼此相同或彼此不同;从而使药剂在聚乙炔中分布。
聚乙炔在处理前必须进行掺杂,掺杂的方法可以是将聚乙炔简单地浸入纯保护剂、液体或其溶液中。经过处理的聚乙炔会在其中分布保护剂。
