Abstract

Cast articles are prepared by homogenizing, at between 50 DEG and 80 DEG C., a mixture of 35-80 parts by volume of a powdered polymerized ethenoid compound and 65-20 parts of a liquid ethenoid monomer, or mixture of monomers, which is a solvent for the polymer and has dissolved or dispersed in it a photopolymerization catalyst, both components of the mixture being free from peroxides or other thermal catalysts, and polymerizing the monomer(s) by means of light. Preferably, the powdered material is such that it will pass through a screen of sieve opening 0.84 mm. and a wire gauge of 0.42 mm. diam., and be retained on a screen of sieve opening 0.30 mm. and a wire gauge of 0.188 diam. It is also preferred that the powdered material is a polymer of the monomer or monomers used, esters of acrylic and substituted acrylic acids, especially methyl methacrylate, and vinyl acetate and styrene being specified. Peroxides and other thermal catalysts may be destroyed in the polymerized ethenoid compound by heating and, if desired, malaxating at 120-180 DEG C. before admixture with the monomer. Specified photopolymerization catalysts are benzoin, uranyl acetate and nitrate and benzyl alcohol. The process may be used to manufacture cast moulded articles, e.g. lenses, and for jointing or filling up holes in sheets of polymethyl methacrylate. Examples are given. Specifications 427,494, 450,305, 550,236 and 569,684 are referred to.
