Polyaddition of Bifunctional Dithiocarbonates Derived from Epoxides and Carbon Disulfide. Synthesis of Novel Poly(thiourethanes)

Polythiourethanes [CSOCH(CH 2 SCOCH 3 )CH 2 O-R-OCHCH(CH 2 SCOCH O CSNH-R'-NH] n (R= PhC(CH 3 ) 2 Ph, PhSO 2 Ph; R'= CH 2 PhCH 2 , (CH 2 ) 6 ) have been synthesized by polyaddition of dithiocarbonates with diamines followed by treatment with acetic anhydride
