ABSTRACT:
A process and apparatus for the continuous mass polymerization of styrenic and alkenylnitrile monomers. The process comprises the steps of continuously introducing a feed comprising a predetermined ratio of styrenic and alkenylnitrile monomers into a reaction vessel to produce a reaction mixture; subjecting the reaction mixture to conditions of temperature and pressure under which said monomers copolymerize to produce a styrenic/alkenylnitrile copolymer; subjecting the reaction mixture to sufficient agitation; continuously withdrawing styrenic/alkenylnitrile copolymer from the reaction vessel; and devolatilizing the styrenic/alkenylnitrile withdrawn from the reaction vessel by a two-stage procedure including first adjusting the ratio of styrenic to alkenylnitrile monomer therein followed by heating to volatilize the volatile components and then separation of volatile components.
