主 题:Colored diol Extender Polycaprolactonediol N N-bis(2-hydroxyethyl)-4-nitroaniline Yellow polyurethane
摘 要:A novel and facile method toward a series of yellow water-borne polyurethane was developed by using an intrinsically colored diol in this *** yellow aqueous dispersion PCLD-HENA-PU was synthesized based on isophorone diisocyanate(IPDI), polycaprolactonediol(PCLD) and 2,2-dimethylol propionic acid(DMPA) using a yellow diol N,N-bis(2-hydroxyethyl)-4-nitroaniline (HENA) as a chain *** to the complete reaction of OH group in colorant HENA with NCO group in diisocyanate,a series of stable yellow p...
