Method for production of unsaturated oligoarylether ketones |
| abstract |
FIELD: industrial organic synthesis. SUBSTANCE: oligoarylether ketones that can be used for production of various-destination heat-resistant polymers ate prepared from aromatic ethers by condensing them directly with maleic anhydride in presence of AlCl 3 catalyst. EFFECT: simplified production of unsaturated aromatic oligomers. 7 ex |
