4 was followed except that 10 4 g of amidoamine prepared from isophthalic acid and jeffamine edr 192 amine 50 ml of water and 2 0 g of adipic acid were used a brown polyether amide was obtained which would swell in water it was drawn into fibers reaction of adipic acid with amidoamine from isophthalic acid and jeffamine edr 148 amine to a test tube were charged 3 3 g of amidoamine prepared from isophthalic acid and jeffamine edr 148 amine and 1 06 g of adipic acid the test tube was placed into a glass reactor equipped with a nitrogen purging tube the reactor was heated to 170 u00b0 c for three hours and 240 u00b0 c for two hours a yellow polyether amide was obtained it swelled in water and was drawn into fibers an alternate way to synthesize polyamides such as the ones of this invention which contain terephthalic amide and can absorb water well will now be described amidoamine prepolymers of jeffamine edr amines with terephthalic acid were reacted directly with a stoichiometric amount of the amidoacid prepolymers of jeffamine edr amines with dibasic acids respectively the products are either sensitive to water or completely soluble in water moreover polyamides have also been prepared from amidoamine prepolymers jeffamine edr amines and dibasic acids in the presence of water which could help create a homogeneous solution the resulting polyamides have.
