制备了含有吡啶基的四种聚合物,并研究了用其制成的湿敏元件的电特性。这些聚合物是季铵化乙烯基毗啶与苯乙烯的共聚物、部分季铵化的聚乙烯基吡啶、与季铵化聚乙烯基毗啶接枝的聚四氟乙烯和与丁基二溴交联的聚乙烯基吡啶,后两种聚合物呈现出优良的抗水性及感湿性。
Four polymers containing pyridyl groups were prepared and the electrical properties of the humidity-sensitive elements made from them were investigated. These polymers are copolymers of quaternized vinyl pyridine with styrene, partially quaternized polyvinylpyridine, polytetrafluoroethylene grafted with quaternized polyvinyl pyridine and with dibutyldibromobutane The latter two polymers exhibit excellent resistance to water and humidity.
