Conclusions
-
1.
A polymer is formed (2% yield) under the effect of heat, UV light, or γ irradiation of the crystals despite the prohibition of the occurrence of topochemical solid-phase polymerization in single crystals of 3,5-octadiyne-1,8-diol bismethacrylate. The molecular weight of the polymer is 3·103–104. This reaction takes place at C≡C-C≡C bonds. C=C bonds are not affected.
-
2.
According to the data from resonant Raman spectroscopy, the structure of the main chain of the polymer formed is intermediate between polyenyne and polybutatriyne (for samples exposed to heat or UV radiation). Chains of enyne structure are also present in the samples prepared by60Co γ irradiation.
