发明名称	Cyclic tri(phenylene disulfide) polymers and the production thereof
摘要	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.
