Hybrid polyion complex (HPIC) micelles are nanoaggregates obtained by complexation of multivalent metal ions by double hydrophilic block copolymers (DHBC). Solutions of DHBC such as the poly(acrylic acid)-block-poly(acrylamide) (PAA-b-PAM) or poly(acrylic acid)-block-poly(2-hydroxyethylacrylate) (PAA-b-PHEA), constituted of an ionizable complexing block and a neutral stabilizing block, were mix...

Polymer composite of heat cure acrylic (PMMA) matrix reinforced with different weight nanoparticles Hydroxyapatite and Magnesium Oxide (1, 5 10% wt.) were prepared by hand molding technique. The oxide synthesized Simple Chemical Method (Co-precipitation). structure morphology properties MgO examined X-ray diffraction (XRD), Field Emission Scanning electron microscopy (FESEM) EDX. Lattice consta...

The complex of polyacrylic and polyurethane films physical mechanical properties the operational leather decorated with them has been studied. polyacrylate protective coatings formation is performed on grain face semi-finished leather. 
 150–200 µm thick are formed from polymer solutions aqueous dispersions. Acrylic obtained a dispersion methylbutylacrylate modified by acrylic lcarboxyetha...

Combinatorial libraries have become increasingly popular in the field of functional biomaterials. One approach for creating diverse polymer libraries is polymer-analogous conjugation of functional groups to polymer scaffolds. In this study, we show that a water-soluble condensing agent, 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMTMM), can be employed to conjugate two ...

Statement of problem. Acrylic resin is most commonly used for denture bases. However, acrylic resin has week points of volumetric shrinkage during polymerization that reduces denture fit. The expandability of POSS (Polyhedral Oligomeric Silsesquioxane) containing polymer could be expected to reduce the polymerization shrinkage of denture bases and would increase the adaptability of the denture ...

The effect of γ-radiation dosage on the thermal stability cross-linked acrylic polymer "Carbomer-140" (СRB) was investigated. DTA, TGA, and DTG curves show multistage processes occurring in different temperature ranges heating CRB from 25 °C to 500 °C. rates decomposition were determined 40–110 °C, 180–260 260–330 330–500 In combination with results electronic structure calculations, potential ...
