POLYMERIC COMPOSITION FOR ARTISTIC-MOSAIC PLATES Russian patent published in 1997 - IPC

FIELD: polymeric compositions. SUBSTANCE: invention relates to polymeric compositions based on unsaturated polyester resins. Polymeric composition has unsaturated polyester resin, accelerating agent - 10-16%-th cobalt naphthenate solution, initiating agent, filling agent. Unsaturated polyester resin is a product of condensation of maleic anhydride, norbornen-2,3-dicarboxylic acid anhydride, diethylene glycol and propylene glycol dissolved in styrene up to viscosity 75-80 s; initiating agent is an isopropylbenzene hydroperoxide. Composition has additionally product based on mixture of dioxane alcohols and their high-boiling esters at flash point 130-140 C obtaining by distillation from flotoreagent light fraction at boiling point 115-160 C under pressure 5-10 mm mercury column. Polymeric composition has the following components, mas. p.: indicated unsaturated polyester resin 600-860; 10-16%-th solution of cobalt naphthenate 42-60; isopropylbenzene hydroperoxide 30-42; filling agent 12.9-560; indicated product based on mixture of dioxane alcohols and their high-boiling esters 56-80. Impact viscosity is increased by 2-2.8-fold and additional styrene addition increases this index by 4-7% additionally. EFFECT: improved quality and properties, broadened spectrum. 2 cl, 1 tbl
