This paper reports the synthesis of ionic liquids through interaction between diethanolamine and orthophosphate boric acids in order to establish possibility replacing volatile coalescents a formulation for paints varnishes with ionogenic compounds. The results from studying influence polymeric based on rheological properties water-dispersion different nature are presented. It has been establis...

Nanocomposite pressure-sensitive adhesives (PSAs) composed of polyurethane (PU)/(meth)acrylates reinforced with MoS2 nanoplatelets were prepared by blending aqueous dispersions. MoS2 crystals were exfoliated by sonication in water in the presence of poly(vinylpyrrolidone) (PVP, molecular weight of 10,000 g mol(-1)) to prepare an aqueous dispersion. Waterborne colloidal polymer particles (latex)...

In this report, a new solventless microencapsulation method by synthesizing polyurethane (PU) from polyol and isocyanate during an agglomeration process in a high-speed mixing apparatus was developed. Clothianidin (CTD), which is a neonicotinoid insecticide and highly effective against a wide variety of insect pests, was used as the model compound. The microencapsulated samples covered with PU ...

Waterborne polyurethane (WPU) dispersions were prepared for flame retardant coatings. Specifically, alkoxysilane-capped polycaprolactone-based WPUs synthesized employing the acetone process, and Casein, as a green sustainable additive, was added by two different methods (in situ ex situ). These strategies made possible to evaluate effect of Polyurethane/Casein interaction in final properties fi...

Aseries of water dispersible polyurethanes containing carboxylate anion as the hydrophilic pendant group were prepared from toluene diisocyanate (TDI), 1,4butanediol (1,4-BDO), dimethylol propionic acid (DMPA) and different molecular weight of polytetramethylene glycol (PTMG). IR Spectroscopy was used to check the end of polymerization reaction and characterization of polymer.The effect of PTMG...

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...
