<p>Crystals of ammonium carboxylates are produced by mixing crystals of a carboxyl-bearing conjugated diene such as muconic acid with at least one compound selected from among amines and ammonia in the absence of a liquid medium. The use of an amine having a bivalent group represented by the general formula: -Ar-N=N-Ar’- (wherein Ar and Ar’ are each independently a bivalent aromatic hydrocarbon group) as the above amine component gives a novel photoresponsive polymer which comprises layer crystals of a carboxyl-bearing conjugated diene polymer and the amine intercalated thereinto. Further, a built-up type diacetylene polymer is obtained by subjecting crystals of an ammonium carboxylate prepared from a carboxylic acid and an amine, at least either of which is a diacetylene derivative, to irradiation with light or heating.</p> |
