MODIFIED EVOH RESIN AND METHOD FOR PREPARING SAME

Abstract: the present application provides a modified evoh resin, which is obtained by that evoh resin is blended with a hyperbranched polymer during an extrusion and granulation step and is modified by the hyperbranched polymer; wherein, the hyperbranched polymer is obtained by reacting a hybrid compound containing boron, silicon or titanium with a small organic molecule containing hydroxyl group. the modified evoh resin can not only increase the branching degree of the evoh resin and increase the radiation crosslinking frequency of the evoh resin, but also effectively reduce the amount of boron-containing compound added and significantly improve the forming processing performance and heat resistance without changing the original preparation process.
