| Abstract: | The aqueous polyurethane(PU) for high gloss finishing agents were prepared from isophorone diisocyanate (IPDI) , polypropylene glycol (PPG), polytetramethylene adipate glycol(PTAd), polytetramethylene ether glycol (PTMG) and dimethylol propionic acid (DMPA) as anionic centers. Chain extensions of prepolymers were formed by ethylene diamine (EDA). Their properties were studied, and thermal properties of the samples were measured using differential scanning calorimetry (DSC). The results showed that the comprehensive properties of PU synthesized with PTMG were excellent, so PTMG was chosen to synthesize aqueous PU finishing agents. |
