Titrimetric determination of residual monomers in styrene-acrylonitrile copolymers
Abstract
A titrimetric method for the determination of residual monomers in styrene-acrylonitrile copolymers has been developed. These monomers are extracted into benzene and styrene in the benzene extract is determined by bromination and acrylonitrile by cyanoethylation with dodecanethiol.
