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 per cent by weight, based on the total weight of the effluent, and the unconverted starting materials are recycled to the process.

Abstract: PROCESS FOR THE MANUFACTURE OF ORGANIC POLYMER POLYOL A process for the manufacture of partially dehydrated organic polymer polyol dispersions from the reaction of polyhydroxyl compounds and aqueous polymer dispersions wherein the problem of excessive viscosity is overcome by mixing the reactants with a recycled partially dehydrated polyol polymer dispersion, removing water from the reaction mixture, removing a portion of the partially dehydrated polyol polymer dispersion, and recycling the remainder.
