METHOD FOR MAKING POLYETHERIMIDE |
| 摘要 |
<p>METHOD FOR MAKING POLYETHERIMIDE A method is provided for making polyetherimide for certain bis (nitrophthalimide) and alkali diphenoxides. Higher polyetherimide intrinsic viscosity is achieved if the alkali diphenoxide is employed as a performed substantially anhydrous reaction product of a diphenoxide and a sodium alkoxide in a C (1-3) alkanol.</p> |
