Abstract: The monomers and opt. solvents and other polymerisation auxiliaries are charged continuously into a polymerisation zone and the liq. polymers are continuously discharged from the polymerisation zone. Volatile components are discharged from the gas compartment of the polymerisation zone, condensed and re-introduced into the polymerisation zone. Improvement comprises rinsing the surfaces defining the gas compartment of the polymerisation zone with the condensed constituents and opt. with the monomers to be charged to the polymerisation zone. Process can be used in styrene copolymerisation with (meth)acrylonitrile; in alpha-Me styrene and acrylonitrile copolymerisation and in styrene and acrylonitrile graft copolymerisation in the presence of elastomers. The formation of insoluble "popcorn" polymers on gas compartment walls is prevented.
