title: Possibilities of quercetin insertion into poly(N,N-dimethylacrylamide-co-3, 9-divinyl-2, 4, 8, 10-tetraoxaspiro (5.5) undecane) network.
abstract: The study presents the possibility of coupling quercetin into poly(N,N-dimethylacrylamide-co-3, 9-divinyl-2, 4, 8, 10-tetraoxaspiro (5.5) undecane) (PDMA-co-U) gel network through a semi-imprinted procedure in order to obtain a responsive antioxidant composite. A continuous magnetic field was used during quercetin insertion for prearranging the compounds - macromolecular matrix and quercetin - and improving the coupling efficiency of the flavonoid structure into the polymeric network. The new supramolecular systems were characterized by FTIR, SEM and thermogravimetric analyses. The dependence of the swelling degree equilibrium and particle size distribution of the studied chemical structures were also evaluated related to the experimental conditions of preparation.
