Notes:
The crystal structure of p-phenylenediacrylic acid diethyl ester above the transition point was determined at 70°C by x-ray diffraction. No significant differences in molecular arrangement are found between the structures of the α2 form (above the transition point) and the α1 form (at room temperature). Since the α1 form is photopolymerized, it is concluded that selective dimerization in the α2 form results not form the crystal structure of the monomer, but from the deterioration of molecular arrangement by the formation of dimer.
