Cross-linked nanocomposite hydrogels based on poly(acryl amide) and mineral nanoparticles (NP) of hydroxyapatite (HAP), ZnO, TiO2 modified by reactive polymers were synthesized via the technique of polymerization filling. It was shown that physico-mechanical properties of obtained nanocomposites are determined to a great extend by the nature of the modifier of mineral NP.
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.
