(on diamines) of terephthalic acid dichloroanhydride (II) or a mixt. of (I I) and a diphenyl series dichloroanhydride; (3) introducing 2-6 moles (per mole diamine) or a tert. amine (III); (4) stirring the reaction mixt. for 3-70 mins; and (5) recovering the desired prod. from the reaction mixt. Suitable tert. amines (III) are alpha-picoline, beta-picoline, dimethylbenzlamine, dimethylaniline, quinoline, pyridine, triethylamine or N-methylmorpholine. The presence of the tert. amine increases the rate of polycondensation of the reactants and allows the prod. of higher mol. wt. prods. The higher rate of polymerisation also reduces the purity requirements of the solvent compared with prior art processes, and it is possible to obtain high mol. wt. polymers using solvents contg. 0.07 % moisture. The poly-p-phenyleneterephthalamide (co)polymers are polyamides having high thermal stability, mechanical strength and solvent resistance. They are useful e.g. in the prodn. of fibres used for making tyre cords and as a reinforcement for plastics materials.
