A tri(phenylene disulfide) polymer composed of para- or meta-tri(phenylene disulfide) units and units selected from the group consisting of diphenyl ether, bis(phenoxybenzenesulfonyl)benzene and bis(phenoxybenzenesulfonyl)diphenyl ether, is linked together with bivalent radicals selected from the group consisting of isophthaloyl and terephthaloyl radicals. In another embodiment, the tri(phenylene disulfide) can be substituted with biphenylene-2,2'-disulfide.
由苯并二硫化物对位或间位三苯并二硫化物单元和从二苯醚、双(苯氧基苯磺酰)苯和双(苯氧基苯磺酰)二苯醚的群组中选择的单元组成的三(苯并二硫化物)聚合物,与从异苯二甲酰基和对苯二甲酰基基团组成的双价基团链接在一起。在另一种实施方式中,三(苯并二硫化物)可以被双苯基-2,2'-二硫化物取代。
