Phase separation of some acrylonitrile—butadiene—styrene resins

Abstract One model and two commercial ABS (acrylonitrile–butadiene–styrene) resins have been separated into three polymeric phases: polybutadiene, styrene–acrylonitrile copolymer, and styrene–acrylonitrile copolymer grafted onto polybutadiene. A third commercial ABS resin has been separated into two polymeric phases: styrene–acrylonitrile copolymer and butadiene–acrylonitrile copolymer.
