ABSTRACT:
New dinitriles are prepared by reacting an alpha, beta saturated nitrile with an alpha, beta unsaturated nitrile. For this preparation subzero temperatures are preferred. Higher diamines can be prepared by hydrogenating the dinitriles thus obtained, such diamines being reacted with a dicarboxylic acid or a salt, ester or chloride of such an acid to prepare polyamides having an amorphous character, i.e. transparent polyamides.
