Abstract

1458265 Preparing monomer/polymer syrup MITSUBISHI RAYON CO Ltd 7 Jan 1974 [18 Jan 1973] 00604/74 Heading C3P A methyl methacrylate monomer/polymer mixture is produced by partial polymerization followed by cooling effected at least partially by reducing the pressure continuously or intermittently to below the vapour pressure of the monomer-polymer mixture causing it to boil while controlling the bubbles formed by the boiling. This control is effected by cooling the walls of the vapour space of the reactor and by refluxing the evaporated monomer. Further cooling of the product can be effected by mixing with cooler monomer-polymer mixture and/or by circulating through a heat exchanger. An apparatus is shown having separate heating or cooling jackets for the polymerization mixture and vapour spaces.
