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.

New synthesis method to obtain a methacrylic monomer with a pyrylium group

Methacrylic monomers with pyrylium salt derivatives are widely used to detect nucleophilic species. A new synthesis method has been used to obtain a pyrylium salt that is trisubstituted with phenyl groups at positions 2,4, and 6. The phenyl group of the 4-position has a metacrylate group in the para-position. The new synthesis method implies the esterification of 4-hydroxybenzaldehyde, using methacrylic anhydride. The formed compound react with acetophenone to form the pyrylium derivative. The yields of both reactions are greater than those previously reported in the literature.
