There is a need to know the nanostructure of pressure-sensitive adhesive (PSA) films obtained from waterborne polymer colloids so that it can be correlated with properties. Intermittent-contact atomic force microscopy (AFM) of an acrylic waterborne PSA film identifies two components, which can be attributed to the polymer and the solids in the serum (mainly surfactant). It is found that when th...

In this study the formation of water-soluble and water-insoluble complexes between bovine serum albumin (BSA) and biocompatible poly(N-vinyl-2-pyrrolidone-co-acrylic acid) (P(VP-co-AA); 2:1), anionic polymer, was studied at different protein, polymer concentrations and pH values. BSAP(VP-co-AA) complexes were studied by turbidimetric, gravimetric and chromatographic methods. Stability of the pr...

A series of water-soluble polymers and derivatives with chelating groups has been prepared and investigated for the complex formation with various metals. The complexation of basis polymers, such as poly(ethyleneiruine) , poly(vinylamine) , and poly(acrylic acid), as well as copolymers was carried out in homogeneous phase. Membrane filtration allowed continuous or discontinuous separation of th...
