Abstract: The invention relates to a process for the preparation of polyester and alkyd resins from bifunctional and/or polyfunctional carboxylic acids and/or derivatives thereof and from bifunctional and/or polyfunctional alcohols. The reaction is carried out in stirred kettle reactors which are operated discontinuously and equipped with rectifying columns. During the entire reaction an entraining agent is introduced into the reaction mixture below surface level, with thorough distribution, by means of a delivery device in order to improve the transport of the products of the condensation reaction. In addition, the condensation reaction is carried out under an absolute pressure of 1.5 to 10 bar at least until the maximum reaction rate has been reached. The pressure is then reduced to atmospheric pressue at a gradient of -0.05 bar/hour to -5 bar/hour in a second reaction phase. The reaction is continued under normal pressure until the product exhibits the desired properties.
