Study on Synthesis of IPDI-Based Waterborne Polyurethane

Abstract:

An IPDI-based waterborne polyurethane emulsion(WPU) was synthesized by the reaction of polyester glycol(PBA), di-methylol propionic acid(DMPA) with isophorone diisocyanate (IPDI) instead of toluene di-isocyanatotoluene(TDI) because of its low toxicity, low saturated vapor pressure. The factors influencing the properties of IPDI -based WPU were discussed. It was observed that the appearance and properties of the IPDI -based WPU were nearly related with the ratio of NCO/OH(R) and the amount of DMPA.
