radical copolymerization
Obtain of Carboxylic- and Aminocontaining Hydrogels Based on Acryl Amide
Cross-linked hydrogels based on functional copolymers of acryl amide with either acrylic acid or dimethylaminoethyl methacrylate were synthesized. It was studied the influence of the comonomer ratio onto copolymerization kinetics as well as the dependence of the physicochemical and physicomechanical properties of hydrogels on copolymer nature and cross-linking degree. The hydrogel obtained are highly flexible and elastic materials. In terms of swelling rate and degree, they can be attributed to super absorbent polymers.
Cross-Linked Polymer Hydrogels with Embedded Semiconductor Nanocrystals
Cross-linked hydrogels containing metal cations were synthesized via radical copolymerization of hydrophilic monomers and nanocomposite hydrogels were obtained on their basis using in situ sol-gel synthesis of semiconductor nanocrystals directly in hydrogel matrices. The influence of metal ions onto copolymerization kinetics and hydrogel crosslinking degree was studied. It was shown that nanocrystal size depends to a large extent on the density of hydrogel network.
