Abstract
##STR1## (wherein R.sub.1 and R.sub.2 independently stand for at least one member selected from the class consisting of alkylene groups, substituted alkylene groups, cycloalkylene groups, substituted cycloakylene groups, arylene groups, and substituted arylene groups), is a novel diacetylene-nylon salt compound possessing two kinds of ability of solid-state polymerization, and two-dimensional macromolecular crystals are obtained by severally polymerizing the diacetylene moiety and the nylon salt moiety of the compound. A shaped article of hig rigidity is produced by filling a mold with the aforementioned salt and subjecting the salt in the mold to simultaneous application of heat and pressure.
