| titleOfInvention | A method of catalytic production of unsaturated polyester resins |
| abstract | A method of catalytic production of unsaturated polyethers by esterification of acidsnsaturated with glycol or glycols in the presence of a catalyst, followed by polycondensation of the dieesters with the raw materialsnunsaturated, stripping condensation water and dissolving the product in an organic solvent,ncharacterized by esterification of isophthalic and / or terephthalic acid with glycol or triol or polyglycolnor a mixture thereof, is carried out with the molar ratio of saturated acid to component being maintainednglycol, respectively 1.0-1.5: 1.0-5.0, in the presence of oxides and / or tin salt as catalyst in the amount ofn0.02-1.0 parts by weight, based on the amount of the acid component, until the acid number of the diester is obtainednless than 15 mgKOH / g followed by condensation with unsaturated acids or anhydridenunsaturated to obtain the acid number of the product not exceeding 50 mgKOH / g. |
