An Aqueous polyurethane emulsion was prepared from polyether glycol,diisocyantotolucl(TDI) and dimethylol propionic acid(DMPA) etc.The effects of R value(n CON /n oh ) on the properties of emulsion were determined at fixed) DMPA content.Results show that the change of R value has important effects on hydroscopicity,mechanical and thermal properties of emulsion-cast film.
