Abstract:
(EN) Disclosed are a styrene copolymer with a reversible crosslink bond, a preparation method therefor and the use thereof. First, a styrene copolymer with a hydroxyl group is synthesized, and then reacted with a furan derivative monomer to form a styrene copolymer with a furyl group, and the styrene copolymer is then reacted with a polyfunctional maleimide derivative to generate a styrene copolymer with a reversible crosslink bond. The styrene copolymer with the reversible crosslink bond improves the solvent resistance of a styrene copolymer material. The reversible crosslink bond in a styrene copolymer material with a reversible crosslink bond can be broken at a high temperature, and the material has secondary processing properties and can be used repeatedly.
(FR) L’invention concerne un copolymère de styrène à liaison de réticulation réversible, son procédé de préparation et son utilisation. Un copolymère de styrène ayant un groupe hydroxyle est tout d'abord synthétisé, puis mis à réagir avec un monomère dérivé de furane pour former un copolymère de styrène avec un groupe furyle, et le copolymère de styrène est ensuite mis à réagir avec un dérivé de maléimide polyfonctionnel pour générer un copolymère de styrène ayant une liaison de réticulation réversible. Le copolymère de styrène ayant la liaison de réticulation réversible améliore la résistance aux solvants d'un matériau copolymère de styrène. La liaison de réticulation réversible dans un matériau copolymère de styrène ayant une liaison de réticulation réversible peut être rompue à une température élevée, et le matériau présente des propriétés de traitement secondaires et peut être utilisé de manière répétée.
