Procedure

480 g of m-xylylenediamine (MXDA) and 580 g of isophthalic acid (IPA) were mixed with 1.0 kg of water and stirred at 90° C. for 1 hour. After becoming clear, the mixture solution was cooled to 25° C. The precipitate was then isolated by decantation, and vacuum dried at 25° C. for 24hours. 1.0 kg of MXDA/IPA salt was thus obtained.
