Abstract

1,156,424. Cast polymerization of methyl methacrylate. DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT. 9 Feb., 1967 [11 Feb., 1966], No. 6245/67. Heading C3P. Cast sheets or panels are prepared by the bulk polymerization of monomeric methyl methacrylate in the presence of a free radical catalyst, 0À1-10 mol. per cent of at least one cross-linking agent and 0À01-1 mol. per cent of at least one molecular weight regulator. Suitable cross-linking agents include di- or higher-acrylates or methacrylates, methylenebis - acrylamide or -methacrylamide, triacryloyl - perhydrotriazine, divinyl benzene vinyl or allyl esters of unsaturated carboxylic acids, # - vinyl -#- hydroxy - ethyl methacrylate, methacrylic anhydride and di- or higherallyl compounds. Preferred regulators are aliphatic mercaptans such as alkyl mercaptans and esters of mercapto-acetic acid. A minor proportion of another monomer, e.g. an alkyl acrylate or methacrylate, acrylonitrile, styrene or vinyltoluene may be present in the polymerization mixture; additives such as plasticizers; pigments, dyes and stabilizers may also be included. The catalyst may be an azo compound or a peroxide; redox systems are also suitable. If desired, the cast polymerization process can be effected continuously.
