Abstract
Low-temperature photocyclopolymerization of crystalline DPDA and polymerization under high pressures of two crystalline diacetylenes (TS and DCH) with different lattice structure are considered. It was shown that the polymer chain growth is dependent upon strains arising during reaction in the solid phase. These strains increase with the decrease in temperature and (or) rise in pressure because of the hindering of the lattice relaxation. Structure and reactivity of the strained metastable configurations that arise are governed by the crystalline lattice structure.Keywords
