Hydroxy-functional poly(ether sulfonamides) as thermoplastic barrier resins |
摘要 |
Hydroxy-functional poly(ether sulfonamides) prepared by polymerizing an N,N'-dialkyl or N,N'-diaryldisulfonamide with a diepoxide in the presence of a suitable catalyst exhibit high barrier properties. These are suitable for use in the manufacture of articles such as rigid containers and flexible films exhibiting high barrier to oxygen.
