ABSTRACT:
Novel polyether amides are produced by reacting a polyethylene glycol diamine and a first dicarboxylic acid or an ester thereof, with a polyoxyalkylene diamine of molecular weight of at least 500 and a second dicarboxylic acid or an ester thereof, where the polyethylene glycol diamine has the formula NH.sub.2 --(CH.sub.2 CH.sub.2 O).sub.x --CH.sub.2 CH.sub.2 --NH.sub.2, where x ranges from 2 to 6, and where the first and second dicarboxylic acid may be the same or different. Suitable dicarboxylic acids include adipic acid, azelaic acid, sebacic acid, dodecanedioic acid, terephthalic acid, isophthalic acid, t-butyl isophthalic acid, and mixtures thereof. Suitable polyethylene glycol diamines include triethylene glycol diamine (JEFFAMINE.RTM. EDR--148 Amine) and tetraethylene glycol diamine (JEFFAMINE.RTM. EDR--192 Amine), among others. Higher molecular weight polyether diamines are used in addition to these polyethylene glycol diamines to give polyether amides useful in making polymers, including fibers, having unusually good water absorbancy properties. The polyether amides are made by mixing equimolar salts of diamine/diacid pairs and then heating the mixture to condense to the polymer.
