Polyadditions of 1,6-hexanedithiol and 1,10-decanedithiol to divinyl sulfone (DVS) in hexamethylphosphoramide in the presence of triethylamine or potassium fluoride afforded polysulfone-sulfides (IIIa and IIIb) with inherent viscosities as high as 0.8 dl/g. Polymerizations of other dithiols with DVS and distyryl sulfone (DSS) were also carried out, however, only low-molecular-weight polymers were obtained. A series of polymers derived from DVS were highly crystalline and soluble in hot… Expand
