ABSTRACT:
A method which comprises drawing a part of the reaction liquid from a reactor for unsaturated polyesters, bringing the drawn liquid into contact and reaction with a gaseous starting material or a liquid starting material capable of being converted into vapor on reaction, for example, an alkylene oxide by means of tubular mixing and recycling this reaction liquid to the reactor thereby preventing increase in pressure of the reactor. An apparatus which comprises a reactor having a confined or open structure, a tubular mixer where a part of the reaction liquid drawn from the reactor is mixed with a gaseous starting material or a liquid starting material capable of being converted into vapor on reaction, which is blown through a nozzle, to cause a vapor-liquid reaction, and a liquid circulation pump for supplying the liquid drawn from the reactor to the tubular mixer and recycling the vapor-liquid reaction product to the reactor.
