The scientific-technical journal

It is the scientific-technical journal in English in Ukraine discussing actual problems of chemistry and chemical technology. Compared with other chemical journals Ch&ChT is publishing materials of both theoretical and practical values in such fields as analytical, general organic, physical and inorganic chemistry; chemistry of high molecular compounds; materials science and engineering; chemical kinetics and catalysis; technology of inorganic substances; technology of organic synthesis products; chemical technology of processing of combustible minerals; processes and apparatus of chemical and food productions; biotechnology and ecology.

    Reaction kinetics and macromolecule-metal chelate complex formation in metal containing semi- interpenetrating polymer networks based on crosslinked polyurethane and linear polymethylmethacrylate
    (Publishing House of Lviv Polytechnic National University, 2008) Kosyanchuk, Ludmila; Kozak, Nataly; Antonenko, Oksana; Nizelskii, Yury; Lipatov, Yury
    According to DSC and EPR data kinetics of formation of simultaneous semi-interpenetrating polymer networks based on crosslinked polyurethane and linear polymethylmethacrylate with 50:50 and 70:30 ratio obtained in the presence of 3d-metal chelates depends on type of metal. On the other hand system composition determines polyurethane or polymethylmethacrylate selection during formation of complexes with metal b-diketonates. Встановлено, що відповідно до даних ЕПР та ДСК кінетика формування одночасних напівзаємо-проникних сіток на основі зшитого поліуретану та лінійного поліметил метакрилату при співвідношені компонентів 50:50 так, і 70:30, одержаних у присутності хелатів 3d-металів, залежить від типу металу. З іншого боку склад системи визначає вибір макроліганду - поліретан чи полімети-метакрилат при утворенні комплексів з β-дикетонатами металів.
