摘要：

Isophoron diisocyanate (IPDI)-based polyester polyurethane (PU) dispersion in water was prepared in a prepolymer mixing process. Dimethylol propionic acid (DMPA), triethylamine (TEA), and triethyl tetramine (TETA) were used, respectively, as potential anionic center, neutralizing agent, and chain extender in aqueous phase. The effects of DMPA, butanediol (BD), and nonionic hydrophilic segment, viz. monofunctional ethylene-propylene oxide ether polyol, on the particle size of dispersion and the mechanical and viscoelastic properties of the emulsion cast films were systematically analyzed.
