Liquid Crystalline Polymers Containing Heterocycloalkane Mesogenic Groups. 6. Liquid Crystalline Polymethacrylates and Polyacrylates of Trans 2-(4-Hydroxyundecanyloxy)-3,5-Dimethylphenyl)-5-(4-Methoxyphenyl)-1,3-Dioxane.

Abstract

The synthesis and characterization of polymethacrylate and polyacrylate of trans 2-(4-(11-(hydroxyundecanyloxy-3, 5-dimethylphenyl)-5-(4-methoxyphenyl)-1,3-dioxane is presented. Both polymers exhibit nematic mesophases and do not present side-chain crystallization. At temperatures higher than 160 C the 1,3-dioxane-2,5-diyl groups undergo a thermally induced trans-cis isomerization. A radical mechanism was proposed for this isomerization. Keywords: Polyacrylates.
