Abstract

Effect of synthesis conditions on the structure and optical properties of hybrid copolymers based on Ti(OPri)4 and hydroxyethyl methacrylate was determined. Raising the concentration of the methacrylic monomer in the system leads to a longer hydrolytic polycondensation of titanium alkoxide and faster radical polymerization of the organic monomer. Copolymers containing poly(titanium oxide) with a nearly anatase structure were obtained in the conditions of a double-stage synthesis including successive stages of low-temperature hydrolytic polycondensation and polymerization. In the case of a single-stage synthesis at 70°C, which combines simultaneously occurring polycondensation and polymerization processes, the copolymer contains the anatase (75%) and rutile (25%) forms of poly(titanium oxide).
