| titleOfInvention | Process for preparing high molecular weight polycondensates |
| abstract | To prepare nitrogen-containing polycondensates, a starting product which still contains reactive end groups is dispersed in a high-boiling, inert solvent, preferably in the presence of a dispersing agent, and low-molecular-weight by-products are distilled at elevated temperature, the batch is cooled and the dispersed polycondensate is isolated. To produce the starting product, a mixture of at least two monomers reacting with one another is heated to a constant reaction temperature, a melt being formed at least in part, but initially no homogeneous melt occurs. The reaction is continued until a homogeneous melt is obtained. Then the precondensate formed is dispersed in the high-boiling inert solvent and condensation is completed. |
