“…Так, розроблено кополімери стиролу з нонiлметакрилатом (СТ-НМА), легованi, наприклад, ациламiнофенiлметакрилатами, які використовуються як електроночутливі шари в мікроелектронних приладах. Як було показано, iмiдофенiлметакрилати мають кращу термостабілізуючу дію порiвняно з ациламiнофенілметакрилатами, і саме тому ці мономери знайшли використання як внутрішньоланцюговi термостабiлiзатори кополімерів, що застосовуються в приладах для мікроелектроніки [2,3].…”

“…Вступ. Створення новітніх матеріалів, зокрема композитів, що складаються із полімерної матриці та органічного барвника, які характеризуються фотопровідністю у видимій ділянці світла, є вельми актуальним завданням для їх практичного використання у фотоелектричних перетворювачах сонячної енергії, модуляторах і перемикачах світлових потоків, пристроях запису, зберігання й обробки оптичної інформації [1][2][3][4][5][6][7]. Значний прогрес досягнуто в контролі фотофізичних та електрофізичних властивостей таких композитних матеріалів шляхом зміни хімічної структури барвників та полімерів.…”

It's known that polystyrene is one of the most widely used plastics. The materials based on it are used in almost all branches of engineering and human's daily life. Therefore, the creation of new highly effective thermal stabilizers for polystyrene remains as the actual task of polymer chemistry. Combining fragments of basic industrial monomer with the modifiers in the polymer matrix provides the ability to control performance properties of obtained materials. Investigation of thermostabilitive action of new styrylquinoline containing methacrylic monomers on polystyrene have been described in this work. Polystyrene and copolymers based on styrene and new methacrylic styrylquinoline containing monomers were synthesized by free radical thermoinitiated polymerization. 2,2´-Azo-bisisobutyronitrile (1 mass per cent) was used as initiator. Styrylquinoline monomers (3 mol per cent) were added to styrene for making modified samples. Polymerization was carried out by heating of reactants in ethyl acetate during 16 hours. Polymers were precipitated in isopropanol and dried at vacuum. The impact of such dopants – 2-[2-(4-methoxyphenyl)ethenyl]quinolin-8-yl 2-methylpropyl-2-enoate (М1), 2-(2-phenylethenyl)quinolin-8-yl 2-methylpropyl-2-enoate (М2), 2-[2-(4-nitrophenyl)ethenyl]quinolin-8-yl 2-methylpropyl-2-enoate (М3) were investigated. Thermostability of polystyrene and modified samples styrene:M1, styrene:M2, styrene:M3 were studied by dynamic thermograviametric analysis. It was shown that destruction of polystyrene with dopants M1-M2 starts at 41–42°С higher than reference polystyrene prepared at the same conditions and polystyrene of brand STYRONE (Switzerland). Sample with dopant M3 begins destruction with lower speed than reference polystyrene. First one loses 20% of weight at 347°С while reference polystyrene loses 50% of weight. It means, that dopant M3 can act as retarder of thermal destruction of polystyrene. It was found that new monomers have thermal stabilizing effect after its covalent introducing and can act as effective inhibitors of thermodestruction of polystyrene in the air.

Polymers, composites, their components and complexes for application in information tecnologies and biotechnology as well as for medicine and solar energy transfer have been obtained. In particular, new high-resolution photochromic polymer materials with a significant nonlinear optical effect of the third order have been developed. They are perspective for the creation of high-speed optical switches in optical recording and information storage. A new way of recording information based on the generation of the second harmonic with new photochromic polymers has been found. The perspectivity of alken-functionalised poly(phenyl/naphthylmethacrylates) as basic compounds for polarization-sensitive polymeric media was prooved.The chemical modification of polymers by benzenesulfonamide derivatives for biostabilization of plastic masses and providing hydrophilic properties for their surface was carried out. A fundamentally new approach is developed in which processes of energy transfer of excited states in polymer macromolecule to the photostabilaser are used for effective stabilization of polymer materials. Thermostabilized samples of polystyrene with covalently bonded of imidophenylmethacrylates have been developed. The branched copolymers are highly efficient matrices for the synthesis of stable gold, silver, CdS and Au / CdS nanoparticles and copolymers that can be used as nanovectors for the target delivery of highly toxic antitumor drugs. New effective preparations for desinfaсtion of fish nurseries, dressing and hygienic materials, linen and clothes have been developed.
