Abstract:

The semi-IPN between starch and biodegradable PCL or PHBV was prepared by using HDI as the cross linking reagent under solution conditions. Their water\|resistance properties were investigated by comparing with cross-linked starch net works without PCL or PHBV. It was found that the water resistance of the Semi\|IPN can be further improved by means of heat treatment or solvent treatment methods, respectively.

Key words: Semi-IPN; Starch; Water-resistance
