FIELD: inorganic chemistry, polymers. SUBSTANCE: method involves pouring in form made of silicate glass and the following hardening the composition containing, mas. p. p.: C 4 - C 8 -alkyl-acryalte, 40-70; methylmethacrylate or butylmethacrylate or their mixture, 29-60; chlorinated polyvinyl chloride-base dry-rolled paste filled with carbon, 0.02-0.035; monomethacrylate ethylene glycol, 5-7; triallylisocyanurate, 0.1-0.5; methacrylate methylmethyldiethoxysilane, 0.1-0.5; dicyclohexylperoxy, dicarbonate 0.08-0.15. Hardening is carried out by temperature increase from 18-28 C to 65-75 C for 2-3 h. EFFECT: improved method of producing. 3 cl |
