Abstract
Process of copolymerization in continuous mass of styrene and methyl methacrylate, characterized in that a mixture of two monomers to be copolymerized, in the form of a thin layer, is passed continuously between two diathermal walls during a reaction time of approximately 15 minutes to 3 hours, at a constant reaction temperature comprised between 130 and 200º C and corresponding for the copolymer formed to a value k according to Fikentscher between 50 and 80, having the ratio of the surface S of heat exchange of the two diathermal walls with respect to the thickness e of the mixture of monomers circulating between them, referring to the volume unit of the mixture, a value expressed in CGS units of at least 0.1 cm-2, is collected, at the exit of the diathermal walls, a mixture containing 60 to 80% of styrene-methyl methacrylate copolymer, and this copolymer is separated from the mixture.
