It was convenient preparative method of new methacrylic monomers with banana-shaped structure and photoactive azomethine fragments synthesis. To determine the effect of large azomethine fragment on the process of homopolymerization, symmetrical model compounds with simpler structure were synthesized. The kinetic of its thermally initiated radical polymerization in DMF solution was studied and compared with the kinetics of model compounds does not containing bulky photochromic fragment. Peculiarities of photo initiated processes of E,Z-isomerization were studied.
