Subject gelatination mechanism

To increase the starch load up to 40-60% in PO a gelatinized starch is used in the films of poly(ethylene-co-acrylic acid) (EAA) or a mixture of EAA/LDPE or LDPE/EMA (ethylene-maleic anhydride). The difficulty with this system is that the high level of filler seriously impairs the mechanical properties, especially in thin films, and the starch is subjected to moisture-absorption problems. LDPE Mn stea-rate/starch showed a decrease of MW during thermo-oxidation and an increase of MW during UV irradiation. In the mixtures, it has been estabhshed that ethylene-acrylic acid copolymer accelerates LDPE oxidative degradation while plasticized starch inhibits it [62]. [Pg.501]
