CURED FLUORENYL POLYIMIDES |
摘要 |
<p>A thermally cured polyimide is provided, and in particular a crosslinked polyimide, comprising a fluorenyl diamine and comprising an aromatic ring having at least one C1-C10 branched or unbranched alkyl substituent, where the alkyl substituent includes a benzylic hydrogen. The present invention provides a crosslinked polyimide made by a process comprising the step of crosslinking a polyimide comprising diamines comprising pendent fluorenyl groups and comprising aromatic rings having at least one C1-C10 branched or unbranched alkyl substituent, the alkyl substituent including a benzylic hydrogen, by raising the temperature of said polyimide above its glass transition temperature.</p> |
