PVC脱HCl制类聚乙炔导电聚合物研究进展

ADVANCES IN PREPERATION OF POLYACETYLENE-LIKE CONDUCTING POLYMER BY CHEMICAL DYHYDROCHLORINATION OF POLY(VINYL CHLORIKE)

对近年来用聚氯乙烯化学法脱氯化氢制备类聚乙炔导电聚合物的研究方法、产物结构性能、产物稳定性及导电性等内容作了简要介绍及评述。

This paper has introduced the principle and methods for chemical dehydrochlorination of poly (vinyl chloride) (PVC) including reactions on inorganic bases or organic bases with PVC.The development and present state on preperation of polyacetylene (PA)and PA like conducting material by dehydrochlorination of PVC were reviewed with 32 references.The most important methods in the PVC dehydrochlorination were(1)the application of phase-transfer catalysis,(2)reactions with strongly organic bases,(3)chemical dehydrochlorination in the presence of a matrix polymer.The preparation methods and their correlation with stability and conductivity,and the existing problems for the materials by dehydrochlorination of PVC were discussed.
