Study on water resistant performance of soy protein isolate biodegradable material by modification

The soy protein isolate was modified with epoxy chloropropance, and a biodegradable material was produced. The factors which influence the water resistant performance of soy protein isolate biodegradable material were studied. The results show modification with epoxy chloropropance, catalyzed by o-Phthalic anhydride, has outstanding effects on the water resistant performance of this material.
