Interaction between aqueous dispersion of anionic polyurethane and gelatin was investigated by UV and FTIR spectrometry.A complex formed by Coulomb forces was found in the solution around pH4 6.The influences of weight ratio
pH values
temperature and electrolyte on the mixed system were studied
and parameters(such as temperature
ionic strength)have a considerable impact on the formation of compleies as well.H bond played a part role in the compatibility of the mixed system.The best compatibility was attained in the mixed system at weight ratio 50/50~40/60(gelatinAPU).
