Process for the manufacture of polyester imides using melamine as the
polyamine reactant
摘要:
Process for the manufacture of polyester imides. Melamine, an at least tribasic carboxylic acid, a polyhydric alcohol and, optionally, an aromatic dicarboxylic acid are condensed at elevated temperature. The polyester imides are suitable, in the form of solutions, aqueous dispersions or melts, for use as baking enamels for metallic conductors.
