Kinetics Studies of Synthesis of Double Bond of Blocked Water-Borne Polyurethane

Abstract:

With isophorone diisocyanate (IPDI) and polyether diols (N210) as raw, the water-borne polyurethane was synthesized. The end groups of the water-borne polyurethane were blocked with 2-hydroxyethyl acrylate (HEA). The chemical structures were characterized from Fourier Transform infrared spectroscopy (FTIR). The viscosity of the emulsion was investigated from rotary viscometer. The kinetics of reaction of NCO blocked with HEA was investigated, the results show that the reaction fits to a second-order reaction characteristic and the reaction rate is irrelevant with HEA.
