Title: Poly(urethane) cationomers from poly(propylene) glycol and isophorone diisocyanate: emulsion characteristics and tensile properties of cast films
Abstract: Poly(urethane) (PU) cationomers were synthesized from poly(propylene) glycol (PPG), isophorone diisocyanate (IPDI), and N-methyldiethanolamine (MDEA) following a prepolymer mixing process. Emulsions were obtained by adding water to the prepolymer solutions. Particle size and emulsion viscosity were studied in response to the MDEA content, degree of neutralization, and solid content of emulsion. It was found that at fixed solids content emulsion viscosity can be varied over 100 times depending on the MDEA content of the prepolymer and the degree of neutralization with acetic acid. Tensile properties of the emulsion cast film showed the increase in modulus and strength with degree of neutralization, as well as MDEA content.
