Ethylbenzene → Prop-2-enenitrile--ethenylbenzene (1/1)

Participants

Reaction Conditions

Reaction Steps

A mixture of 73 parts styrene and 27 parts acrylonitrile is continuously fed to a stirred polymerization reactor. 50 parts of ethylbenzene are also added as a diluent along with 0.5 parts tert-butyl perbenzoate catalyst. The reaction mixture is heated to 110° C., and the monomers are polymerized by continuous mass polymerization until the initial continuous monomer phase is inverted to form a continuous styrene-acrylonitrile copolymer matrix with residual monomer dispersed throughout the matrix.
