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.

    Selected radical azoinitiators in the synthesis of solvent-borne acrylic pressure-sensitive adhesives
    (Publishing House of Lviv Polytechnic National University, 2009) Pabin-Szafko, Barbara; Wisniewska, Ewa; Czech, Zbigniew
    Functional azoinitiators: 2,2’-azobis(2-methyl- 4-hydroxybutyl propionate) (AIB-BD), 2,2’-azobis[2- methyl-?-hydroxy-tri(oxyethylene) propionate] [AIBTri(OE)] and 2,2’-azobis[2-methyl-?-hydroxyoligo( oxyethylene) propionate] [AIB-OOE(400)] were used in radical polymerization of 2-ethylhexyl acrylate, methyl acrylate and acrylic acid in organic solvent ethyl тacetate to prepare solvent-borne acrylic pressure-sensitive adhesives (PSA). After polymerization the viscosity, molecular weight and polydispersity of received acrylic PSA have been evaluated and compared with the product of polymerization initiated by the conventional azoinitiator 2,2’-azobisisobutyronitrile (AIBN). Показана можливість використання функційних азоініціаторів: 2,2’-азобіс(2-метил-4-гідроксибутил пропіонату), 2,2’-азобіс[2-метил-ω-гідрокси-три(оксиетилен) пропіонату] та 2,2’-азобіс[2-метил-ω-гідрокси-оліго(оксиетилен) пропіонату] в радикальній полімеризації 2-етилгексилакрилату, метилакрилату і метакрилової кислоти в органічному розчиннику етилацетаті для одержання обмежено розчинних акрилових клеїв, здатних склеюватись при надавлюванні.
