Abstract

Disclosed is a diacetylene compound comprising, as structural units, (a) at least one member selected from diacetylene group-containing organic groups of the formulae (I) and (II): R.sup.I --C.tbd.C--C.tbd.C--R.sup.II -- (I) and --R.sup.III --C.tbd.C--C.tbd.C--R.sup.IV -- (II) wherein R.sup.I is hydrogen or a (Cl-16) monovalent organic group, and R.sup.II, R.sup.III and R.sup.IV are a (C1-13) divalent organic group, (b) at least one organic group having at least one carbon-to-carbon double bond, and (c) at least one connecting group connecting the units (a) and (b), which connecting group is selected from amide, imide, ester, ether, amino, imino, urethane, sulfonyl and carbonyl bonds. A cured shaped article made of this compound exhibits isotropically a high elastic modulus and has excellent mechanical properties.
