| abstract |
The invention relates to an additive for the controlled adjustment of the viscosity of polycondensates, comprising an acid and/or an acid anhydride as well as a carrier, preferably a polymeric carrier, characterized in that the acid and/or the acid anhydride is/are evenly distributed in the carrier. The invention also relates to a method for producing the additive, a method for the controlled adjustment of the viscosity of polycondensates, and the use of the additive for the controlled adjustment of the viscosity of polycondensates. |
