ABSTRACT:
An economical and environmentally advantageous process for the continuous manufacture of unsaturated polyesters, wherein the vapors formed during the polycondensation are purified, in a two-part distillation column, to a degree where the residual content of organic starting materials is less than 1.5 percent by weight, based on the total weight of the effluent, and the unconverted starting materials are recycled to the process.
