    摘要： A continuous process for producing rubber-modified methyl methacrylate syrups which comprises continuously supplying a material liquor comprising 1 to 20 parts by weight of a rubbery polymer dissolved in 100 parts by weight of a monomer comprising 60 to 100% by weight of methyl methacrylate, and a radical-polymerization initiator to the first reaction zone, continuously polymerizing at such a stationary conversion that the rubber polymer is dispersed in the form of particles form while maintaining the temperature and residence time in the zone so that a steady state is achieved in the zone and the steady-state concentration of the initiator in the zone is 1/2 to 1/1,000 time as much as the concentration of initiator supplied, continuously taking out the resulting reaction mixture from the zone, and passing it through the second reaction zone having a volume of 0 to 5 times as much as that of the first reaction zone, to obtain a stable syrup comprising a disperse phase and a continuous phase, the former phase being substantially a solution of the rubbery polymer in the monomer and the latter one being substantially a solution of the resinous polymer in the monomer, and a process for the production of methyl methacrylate cast sheets and molding materials having an excellent impact resistance from the syrups.

    摘要： A process for the production of a thermoplastic copolymer having excellent heat distortion resistance is disclosed. The process includes heat-treating a raw copolymer comprising a vinyl monomer unit including methacrylic and/or acrylic acid units in the presence of a specific ring-closing promoter selected from basic compounds, whereby the methacrylic and/or acrylic acid unit is converted into six-membered cyclic anhydride unit. The copolymer has excellent heat distortion resistance, transparency, mechanical properties and processability, and can produce a formed product without splash on the surface. The copolymer is useful for the production of various parts, such as automobile parts, electrical parts, industrial parts, and miscellaneous goods.
