摘要 |
<p>A modified ethylene-vinyl alcohol copolymer (C) contains 0.3-40 molar% structural units (I) and has 5-55 molar% ethylene content. A modified ethylene-vinyl alcohol copolymer (C) contains 0.3-40 mol% structural units of formula (I) and has 5-55 molar% ethylene content. R 1> - R 4> = H, 1-10C aliphatic hydrocarbon gp., 3-10C alicyclic hydrocarbon or 6-10C aromatic hydrocarbon (all opt. containing OH, carboxyl or halogen) (R 3> and R 4> may be bonded together). [Image] An independent claim is also included for production of the modified copolymer, comprising reacting an ethylene-vinyl alcohol copolymer (A) with a monovalent epoxy compound (B) having at most 500 mol.wt.</p> |
