New poly-o-quinonemethacrylate and its dioxygen-active antimony-containing polymer

o-Benzoquinonemethacrylate QMet is prepared by the reaction between 3,6-di-tert-butyl-o-benzoquinone and monomethacrylic ethers of ethylene glycol. Free radical polymerization of this monomer allows to synthesize polyo- benzoquinones Poly-QMet with molecular weight depending on the polymerization method and concentration of initiator. Polymerization in solution leads to polymer with 22-30 o-benzoquinone fragments in polymeric chain whereas bulk polymerization results in polymer with 110-190 o-benzoquinone fragments in polymeric chain. These polymers can be used in the preparation of metal-containing polymeric catecholate complexes. Triphenylantimony(V) polycatecholate Poly-SbCatMet is prepared by two ways - oxidative addition of SbPh3 to poly-o-quinone and polymerization of monomeric triphenylantimony catecholate SbCatMet. This polymeric catecholate Poly-SbCatMet is able to the reversible absorption of molecular oxygen on air both in solution and in thin film with conversion about 50-65 % (by NMR-spectroscopy and UV-vis data).
