Study on Polyurethane Dispersions with PES/PPG and High-Solid Content

Abstract:

A series of novel stable and high-solid-content polyurethane were prepared by self-emulsification,use PES and PPG as mixed soft segments.Influence of APAETMS content and mole ratio of PES/PPG on properties of polyurethane dispersions and films were analyzed .Results show that: the cross-linked complex were multivariate distribution in particle size. With an increase of the mass ratio of PES and PPG and content of APAETMS average particles diameter of polyurethane dispersions became bigger , poly-dispersion became wider., solid content of dispersions decrease.. It is also noticed that the high-solid-content dispersions exhibit a pseudo-plastic behavior, when the mass ratio of PES and PPG is 1:3 and content of APAETMS is 1%, the solid content of dispersions is up to 55%. The film also has a good shape memory behavior.
