To obtain an optical polymer with a high refractive index ( n D ) and Abbe's number (n D ), a series of 1,4-dithiane-2,5-bis(thiomethyl) (DBT) group-bearing poly( Salkylcarbamate) and polyvinylsulfide were synthesized by the polyaddition of 2,5bis(mercaptomethyl)-1,4-dithiane (BMMD) with diisocyanat
