Properties of waterborne polyurethane/nanosilica composite
Macromolecular Research, 2003Aqueous emulsion of polyurethane (PU) ionomers were reinforced with hydrophobic nanosilica to give composites. The aqueous emulsion was stable and the particle size increased as the content of hydrophobic nanosilica was increased. The reinforcing effect of nanosilica in mechanical properties of these composites were examined by dynamic mechanical and ...

Synthesis of Waterborne Polyurethane for Coating on HNIW
Advanced Materials Research, 2011The waterborne polyurethane (WPU) was synthesized from isophorone diisocyanate (IPDI), polypropylene glycol (PPG), dimethylolpropionic acid (DMPA) and 1,4-butanediol (BDO) under acetone reflux. The cast films obtained from it were characterized by Fourier transform infrared (FTIR), nuclear magnetic resonance (1H NMR) and differential scanning ...

Synthesis and properties of crosslinked waterborne polyurethane
Journal of Polymer Research, 2010Waterborne polyurethane prepolymer was prepared by the reaction of isophorone isocyanate(IPDI), polyether polyol(PTMG), dimethylol propionic acid(DMPA) and trimethylol propane(TMP), which was modified by silicane coupling agent(APTES) to form highly crosslinked polyurethane emulsion. The films of the waterborne polyurethane were prepared. The structure

Improved Adhesion of Waterborne Polyurethanes by Hybridizations
The Journal of Adhesion, 2008Aqueous polyurethane dispersions based on isophorone diisocyanate (IPDI), poly (tetramethylene adipate) glycol (PTAd), and dimethylolproprionic acid (DMPA) were synthesized by a prepolymer mixing process. Effects of the molecular weight of PTAd and types of hybridizations, viz.
