    Abstract: Embodiments of the present invention disclose a process for the co-production of bis(para-aminocyclohexyl) methane (PACM). Also disclosed are articles of manufacture made using PACM produced by methods of this invention. The methods of the present invention generally include a first mixture having methylene di-aniline (MDA) and a second aromatic amine. The first mixture has less than 15% polymeric MDA by weight and the second aromatic amine is present in an amount to render the first mixture a liquid. The first mixture is hydrogenated to produce a product mixture comprising PACM and at least one second non-aromatic amine.

    Abstract: Novel polyether amides produced by reacting at least one polyalkylene glycol diamine with at least two dicarboxylic acids or esters thereof are described. 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 at least one of the dicarboxylic acids is an aromatic discarboxylic acid. These novel polyether amides may have the formula: ##STR1## where each R and R' are independently an alkylene or arylene moiety having from 3 to 34 carbon atoms, where at least one R or R' is an arylene moiety, and where each x and y independently have the values noted. Suitable dicarboxylic acids include adipic acid, azelaic acid, sebacic acid, dodecanedioic acid, terephthalic acid, isophthalic acid, t-butyl isophthalic acid, and mixtures thereof. Suitable diamines include triethylene glycol diamine (JEFFAMINE.RTM. EDR-148 amine) and tetraethylene glycol diamine (JEFFAMINE.RTM. EDR-192 amine), among others. The resulting polyether amides are useful to make polymers, including fibers, with unusually good water absorbancy properties. The inventive methods successfully incorporate triethylene glycol diamine and aromatic dibasic acids, where this cannot be accomplished directly.
