radical copolymerization

Cross-linked nanocomposite hydrogels based on polyacrylamide and mineral
nanoparticles of hydroxyapatite, ZnO, TiO2 previously modified by reactive polymers were
synthesized via the method of polymerization filling. It is shown that physico-mechanical
properties of obtained nanocomposites are determined to a great extent by the nature of the
modifier of mineral nanoparticles. The influence of the nature of mineral filler as well as of
reactive modifier of nanoparticle surface onto colloidal-chemical and physio-mechanical

The series of reactive peroxide macroinitiators (RC) based on acryl amide (AcAm), butyl methacrylate (BMA), maleic anhydride (MA) and peroxidic monomer 5-ter-butylperoxy-5-methyl-1-hexene-3-yne (PM), which can be used for biocompatible polymer cross-linking, were synthesized via radical copolymerization in organic solvent.

Синтезовано просторово зшиті полімерні гідрогелі на основі гідрофільних
кополімерів акриламіду з акриловою кислотою або диметиламіноетилметакрилатом.
Досліджено вплив складу мономерної суміші на кінетику кополімеризації, а також
залежність фізико-хімічних та фізико-механічних властивостей гідрогелів від природи
кополімеру та ступеня структурування. Показано, що отримані гідрогелі є високо-
еластичними, пружними матеріалами, а за швидкістю і ступенем набрякання можуть

Heterometal polymer complexes with -diketonate fragments have been obtained via styrene triple copolymerization with polyfunctional components of radical polymerization – vinyl--diketonates of 5-methyl-5-hexene-2,4-ditionates Mn(II) and Zn(II). The process was carried out in a block and dimethylformamide solution in the presence and absence of additional initiator – benzoyl peroxide. Varying the chelated metals concentration, the presence of solvent and additional initiator one may control the concentration and metal ratio in the macromolecule, as well as products molecular weight.

Bimetallic macroinitiators have been obtained via styrene triple copolymerization with cobalt(II) and manganese(II) vinyl--diketonates. The copolymerization kinetic parameters have been studied. Metal chelates were found to be as comonomers, initiators and inhibitors at the same time during copolymerization process. The macroinitiators synthesis optimal conditions have been examined. They may be used for the production of grafted polymers.
