Abstract

Waterborne polyurethane as a new polymer dispersion was synthesized by using relatively hydrophilic polyols. The polymer was prepared from polycaprolactone (Capa 225), toluene diisocyanate (TDI), 1,4-butane diol (BDO) as a chain extender, and dibutyltin dilaurate catalyst. GRAFTED POLYURETHANE was prepared with chlorinated poly(ethylene glycol monomethylether) (PEGMME) in the presence of NaH catalyst. Chlorinated PEGMME was also prepared by reaction of PEGMME with thionyl chloride in dried toluene. FTIR and 1H NMR of the WATERBORNE POLYURETHANEs were studied. The effects of various molecular weights of poly(ethylene glycol monomethylether) (PEGMME) as non-ionic hydrophilic segments were studied. The PARTICLE SIZE and viscosity of dispersion were systematically analyzed. It is found that by increasing the molecular weight of the grafted PEGMME, the PARTICLE SIZE of the dispersed polyurethane is decreased, and viscosity is increased.
