The development of information technologies requires more concepts for creation new multifunctional materials and study its function-structure relationships. The most important among them are polymer photochromic materials, which can be observed by few ways. The first method is mechanical mixing of polymer matrix and chromophore. The second method involves the covalent introducing of chromophore molecule in the main chain of polymer or as side-on attached [1]. Materials synthesized by second way have some advantages: solubility, film coating, time stability, adhesion, conductivity, etc., and can find application in optics, photovoltaics, photonics, medicine and many others.
In this work we present synthesis and investigation of polymerization activity of new monomers based on 6-hydroxyaurone fragment.  Novel monomers were synthesized by using methacryloyl chloride for acylation 6-hydroxyaurone derivatives at basic conditions and low temperatures. The polymerization ability of the new monomers was investigated kinetically for radical thermal initiated polymerization by dylatometric method. The polymerization was carried out for 10% solution of monomer in DMF with 1% of AIBN as initiator at 80°C. The structure of synthesized compounds was determined by 1H NMR-spectroscopy.
