Poly(urethane-urea)s (PUUs) from 2,4-tolylene diisocyanate (2,4-TDI), poly(oxytetramethylene)diols (PTMO) or poly(butylene adipate)diol (PBA), and various diamines were synthesized and characterized by Fourier transform infrared spectroscopy, gel permeation chromatography, differential scanning calo
## Abstract A series of waterborne poly(urethaneβurea)s, WPUUs, based on using nonpolar hydroxylβterminated polybutadiene (HTPB) as the soft segment, were successfully synthesized in this article. The effects of the COOH group content and softβsegment molecular weight (Mn~s~) on the dispersion, mor
