Aqueous process for the preparation of polyimide resins |
| abstract |
DISCLOSED HEREIN IS AN AQUEOUS PROCESS FOR THE PREPARATION OF POLYIMIDE RESINS WHICH PROCESS COMPRISES REACTING IN AN AQUEOUS MEDIUM: TSP@ (1) BENZOPHENONE TETRACARBOXYLIC DIANHYDRIDE OR BENZOPHEONE TETRACARBOXYLIC ACID AND (2) A WATER SOLUBLE POLYAMINE HAVING AT LEAST TWO PRIMARY AMINO GROUPS PER MOLECULE AT TEMPERATURES OF AT LEAST 60*C. FOR A TIME SUFFICIENT TO FORM RECURRING IMIDE UNITS IN THE POLYMER. |
