The ring-opening polymerization of cyclic (aromatic disulfide) oligomers derived from 4,4Lisopropylidene bisthiophenol was studied both in diphenyl ether solution and in the melt. The polymers formed were soluble in solvents such as chloroform, tetrahydrofuran, DMF, NMP and characterized by n.m.r.,

Copolymerization reactions between cyclic(arylene disulfide) oligomers were studied. The cyclic disulfide oligomers derived from 4,4-isopropylidene bisbenzenethiol gave soluble polysulfanes via copolymerization with S 8 . The copolymerization reactions were studied both in solution and melt by GPC a
