I-chain extender ne-emulsifier yama-aqueous polyurethane dispersions.Kuyi-aliphatic diamine sulfonic acid usawoti we-sodium, osetshenziswa njenge-hydrophilic chain extender noma i-hydrophilic monomer ekulungiseni i-polyurethane resin ephuma emanzini, elungele ukumbozwa, oyinki, okunamathelayo kanye nama-ejenti wokuqeda wesikhumba nezinye izimboni.I-sodium ethylenediaminoethanesulfonate ingasetshenziswa nakweminye imikhakha njengama-organic intermediates kanye nama-reagents e-biochemical.I-X-position kanye namaqembu e-amino asendaweni yesibili angasabela ngamaqembu e-isocyanate futhi avame ukunconywa ukuthi asetshenziswe enqubweni ye-acetone.Ama-polyurethane dispersions ahlanganiswe kusetshenziswa usawoti we-AAS unokusimama okuhle kwe-hydrolytic kanye nokuhambisana okuhle nokunye okuhlakazeka kwamanzi kwe-anionic noma i-nonionic.
