Water-resistant films were prepared by coating a castor oil-based polyurethane-chitosan (PU-CH), in which grafted interpenetrating polymer networks (IPNs) were produced, on a regenerated cellulose (RC) film. The tensile strengths of the coated films cured at 90ЊC for 5 min reached 853 kg cm 02 (dry
