    Matrix polymerization of 2-hydroxyethylmethacrylate in the presence of polyvinylpyrrolidone in permanent magnetic field
    (Publishing House of Lviv Polytechnic National University, 2010) Skorokhoda, Volodymyr
    The influence of a constant magnetic field on the polymerization kinetics and structural parameters of a hydrogel network on the basis of 2-hydroxyethylmethacrylate and polyvinylpyrrolidone compositions has been investigated. It has been shown that the magnetic field activates matrix polymerization of such compositions and assists in structure formation of copolymers withminor density. The efficiency of the developed polymericmaterials used for production of ultrathin contact lenses has been confirmed. Досліджено вплив постійного магнітного поля на кінетику полімеризації та структурніпараметри сітки гідрогелів на основі композицій 2-гідроксіетилметакрилату з полівінілпіролідоном. Виявлено, що магнітне поле активує матричну полімеризацію таких композицій і сприяє формуванню структури (ко)полімерів з меншою густотою сітки. Підтверджена ефективність використання розроблених полімерних матеріалів для виробництва ультратонких контактних лінз.
