| Abstract: | Qualitative and quantitative analysis of the ingredients of Water-borne polyurethane emulsion which usually consists of polyols,diisocyanate,chain extender,salifying agent water and organic solvents and so on,was discussed by multi-analytic techniques such as IR,GPC,GC/LC/MS and NMR.Molecular weight and its distribution were determined by gel permeation chromatogram.The experimental results showed that this kind of water-borne PU was carboxylate anionic type emulsion.Isophorone diisocyanate(IPDI),polyester ... |
