Reprocessable and degradable bismaleimide resin

Abstract

The invention discloses a remodelable degradable bismaleimide resin and a preparation method thereof, which are prepared from 4,4-dithiodiphenylamine bismaleimide (AM), 4-diallyloxy diphenyl Disulfide (DS) and phenolphthalein polyaryletherketone. The bismaleimide resin prepared by the invention not only has excellent heat resistance, but also can realize remolding under the hot-pressing condition, realizes faster degradation in a conventional solvent, and can realize closed-loop recovery by evaporating the degradation solution and heating and pressurizing the solvent, thereby overcoming the defects that the bismaleimide resin containing reversible covalent bonds is difficult to have high heat resistance, remolding and degradability, and providing a new resin and preparation strategy for realizing the sustainable development of heat-resistant thermosetting resin
