FIELD: chemical technology of polymers.
SUBSTANCE: invention describes a plastic molded articles made by polymerization by the molding method of a mixture comprising the following components, wt.-%: methyl methacrylate, 65-99.5; unsaturated carboxylic acid, 0-3; shock-resistant modifying agent, 0.5-35; cross-linking agent, 0-1; stabilizing agent, 0.5-1; initiating agent, 0.001-0.1; lubricant, 0.01-1.0, and regulating agent, 0.001-0.031. In the proposed method a shock-resistant modifying agent is dissolved in methyl methacrylate or partially polymerized methyl methacrylate (syrup) followed by pouring the solution into a chamber. Invention provides preparing the shock-resistance molding material.
EFFECT: improved preparing method, improved and valuable properties of article.
