摘要

本文介绍了含有吸电子和供电子取代基的不同苯乙烯单体的苯乙烯共聚物的耐局部放电性能。聚合物链中五氟苯乙烯(PFS)的存在对PD的抗性有明显的负面影响。初步结果表明，聚苯乙烯本身对PD具有很好的稳定性。给电子对甲氧基苯乙烯单体对PD的稳定性有明显的负面影响。对甲基苯乙烯和对氯苯乙烯与苯乙烯在PD抗性方面没有明显差异。

Influence of chemical structure in styrene copolymers subjected to partial discharges

The authors present data on the PD (partial discharge) resistance of styrene copolymers containing a number of different styrene monomers with electron-withdrawing and electron-donating substituents. The presence of pentafluorostyrene (PFS) in the polymer chain is shown to have a clearly negative influence on the resistance to PD. Preliminary results show that polystyrene itself has a very good stability with respect to PD. The electron-donating p-methoxystyrene monomer has a clearly negative influence on the PD stability. P-methylstyrene and p-chlorostyrene do not differ appreciably from styrene regarding PD resistance.<>
