Process for preparing polyarylates in the presence of a diphenyl ether compound and a magnesium catalyst |
| abstract |
The present invention deals with a process for preparing polyarylates in the presence of a diphenyl ether compound and a magnesium catalyst. n According to the invention, polyarylates are prepared by the reaction of a diester derivative of a dihydric phenol with an aromatic dicarboxylic acid in the presence of from about 10 to about 60 weight percent of a diphenyl ether compound at a temperature of from about 260 to 350°C and in the presence of a magnesium catalyst. n This process provides a polyarylate of acceptable molecular weight with a better removal of the acid by-product in a reactant system having a reduced viscosity. |
