Title:
【発明の名称】エチレンビニルアルコール共重合体(EVOH)の変性からの高められた酸素遮断性能
Document Type and Number:
Japanese Patent JP2003534413
Kind Code:
A
Abstract:
Herein is disclosed a modified ethylene vinyl alcohol polymer (EVOH) comprising an oxygen scavenging functional group. Preferably, the modified EVOH comprises structures IV, V, and VI: wherein x is an integer greater than or equal to 1, y is an integer greater than or equal to 1, z is an integer greater than or equal to 1, and R comprises a cycloalkenyl group. The modified EVOH is useful in oxygen barrier applications, such as a forming an oxygen barrier layer of a packaging article. Also disclosed are methods of modifying ethylene vinyl alcohol polymers, and using the modified EVOH to make packaging articles with a superior barrier to entry by atmospheric oxygen.
