| titleOfInvention | A method for producing unsaturated polyester resins with increased flexibility |
| abstract | The method of producing unsaturated polyester resins is based on a mixture of glycolnor glycols, unsaturated dicarboxylic acid and / or its anhydride, saturated aliphaticnand / or an aromatic dicarboxylic acid and / or their anhydrides and / or their esters, in a molar ration1.0-1.3 moles of glycols per 1 mole of acid components, and vegetable oil or a mixture of oils,nadded in an amount of 5-25% by weight based on the weight of the reaction mixture, and optionallynunsaturated fatty acid or a mixture of C16-C22 unsaturated fatty acids,npreferably in an amount of 5-15 wt.% with respect to the weight of the reaction mixture, heated to temperaturen170-230 ° C, mixing the components under an inert gas atmosphere and collecting low molecular weightncondensation products until a product with an acid number of less than 45 mg KOH / g and temperature is obtainednsoftening 20-60 ° C determined by the "Ring and ball" method, followed by the obtained unsaturated polyesternis dissolved in the cross-linking monomer, or in a mixture of cross-linking monomers. |
