机译:耐氧化乙烯-乙烯醇聚合物组合物

摘要

A composition that exhibits improved stability to oxidative formation of Gel at elevated temperaturesConsisting essentially of: (a) at least one ethylene Copolymer and about 90 to about 50 percent by weight of vinyl alcohol molecules.That has a degree of saponification of at least about 90%; (b) around 0.01 to around 0.5 cientopor Weight of at least one monovalent or divalent metal Salt of an aliphatic carboxylic acid, and (c) around 0.05 to about 0.5 percent by weight of at least one hindered phenolic Antioxidant.
