| 摘要 |
<p>The present invention provides coextruded or laminated multilayer films having at least one layer of a halopolymer such as poly(chlorotrifluoro ethylene) (PCTFE), at least one layer of a naphthalene containing polymer such as poly(ethylene naphthalate) (PEN), and an intermediate adhesive layer. The invention further provides methods of producing oriented, multilayer films which comprise either coextruding or laminating at least one layer of a halopolymer to a surface of at least one layer of a naphathalene containing polymer by an intermediate adhesive layer. The multilayer film may be uniaxially or biaxially stretched, and an optional thermoplastic polymer layer may be attached to another surface of either the halopolymer layer, the naphthalene containing polymer layer, or both, by another intermediate adhesive layer.</p> |
