摘要:
Sulfonated polyester polyols and mixtures of sulfonated polyester polyols and hydroxy carboxylic acids are used to prepare improved aqueous anionic poly(urethane/urea) dispersions with a high crystallization rate, low heat activation temperature, high green strength, stability at low pH, which show good compatibility with other water based polymers and with crosslinkers. The aqueous anionic poly(urethane/urea) dispersions have high heat resistance after curing or blending with a crosslinker.
