    Abstract: Process for the preparation of a carboxylic acid derivative according to general formula (I) where the fragments X are a lactam, an oxime or an imide in the form of HX, by mixing HX with phosgene, with hydrogen chloride being removed in gaseous form from the mixture formed. This can be accomplished by not adding any base to the reaction mixture. The invention also relates to carbonylbiscaprolactam, characterized in that the water content is lower than 250 ppm and the chlorine content is lower than 300 ppm. The invention also relates to a process for increasing the molecular weight of a polymer by mixing an -OH- or -NH2-functional polymer in the melt with a carboxylic acid derivative according to formula (I), characterized in that the carboxylic acid derivative has a water content of less than 250 ppm and a chlorine content of less than 300 ppm.
