Waterborne Polyurethane-Polyacrylate Hybrids
2021Waterborne Polyurethane-Polyacrylate hybrids (WPUAHs) are prepared via various polymerizations methods such as different types of emulsion polymerization. The WPUAHs have various applications because of their appropriate properties. The WPUAHs have been prepared via separate and in-situ methods.

On The Micro‐Phase Separation in Waterborne Polyurethanes
Macromolecular Chemistry and Physics, 2009AbstractSome polyester and polycarbonate‐based waterborne polyurethanes (WPU) were characterised by means of several techniques, to correlate the morphology with their structures and properties. The morphological analysis carried out by transmission electron microscopy on thin sections showed that the selected polyurethanes, after purification, exhibit

Green fluorescent waterborne polyurethane polyols
Colloid and Polymer Science, 2021In this paper, we reported a series of green fluorescent flame-retardant waterborne polyurethane polyols. The polyurethane polyols were uniformly sized and possessed decent colloidal stability. Comparing to other reported products, our aqueous dispersions showed much stronger fluorescence intensity and greatly improved long-term stability, which were ...

Waterborne polyurethanes and their properties
Journal of Polymer Science Part A: Polymer Chemistry, 1996Anionomer-type waterborne polyurethanes (PUs) were obtained from poly(β-methyl-δ-valerolactone) glycol (PMVL) and isophorone diisocyanate, following a prepolymer mixing process. The soft-hard segment phase separation in response to the variations of composition and structure of PU has been studied from the dynamic mechanical measurements of the ...

Surface modification of waterborne polyurethane
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2006Fluorinated urethane oligomers (SMAs) having repeat unit identical to the hard segment of base polyurethane (PU) have been synthesized and blended with base PU prior to dispersion. XPS and static contact angle measurements showed that surfaces of dispersion cast film are significantly enriched with SMA although SMA and base PU were miscible in bulk ...
