Abstract

Abstract: Mercaptomethyl-1,4-dithiane(MMD) and 2-methacrylthiomethyl-1,4-dithiane(MMDMA) were synthesized through hydrochloride/thiourea method and special Phase Transfer Catalysis (dropping caustic solution) at low temperature, respectively. The ring rearrangements of MMDin the synthesis process and the copolymerization property of MMDMAwere discussed separately, thus a new kind optical resins with high refractive index and low chromatic dispersion were obtaind.

Key words: Methacrylthiomethyl-1, 4-dithiane, Phase transfer catalysis, Optical plastics
