Abstract: The N,N-dimethyldithiocarbamide (RS—) end groups of polystyrene are transformable to other functional groups by hydrolysis in acidic or alkaline media. The structure of the hydrolyzed end groups depends both on the kind of catalysis and type of the end carbon atom of the polystyrene chain, on which the functional group is bonded. The RS— group bonded to the secondary end carbon atom (—CH₂—) of polystyrene was chemically transformed into —SH group during alkaline hydrolysis, while as a result of acid hydrolysis, the formation of —S—C(S)—OH end groups was observed. The common feature of acid- and alkaline-catalyzed hydrolysis is quantitative splitting off of the RS— groups bonded to the tertiary end carbon atom of polystyrene.
