Title:
熱硬化性樹脂の回収・再利用方法および変性スチレン-フマル酸共重合体の製造方法
Document Type and Number:
Japanese Patent JP5001017
Kind Code:
B2
Abstract:
To provide a modified styrene-fumaric acid copolymer reusable for a low shrinkage material of a thermoplastic resin.
The modified styrene-fumaric acid copolymer is prepared by subjecting the fumaric acid structure portion of a styrene-fumaric acid copolymer to a condensation reaction. The condensation reaction is conducted by the reaction with acetic anhydride or by the thermal dehydration reaction. The styrene-fumaric acid copolymer is prepared by decomposing a thermosetting resin containing a polyester and its crosslinked portion with supercritical water. Preferably, the decomposition is conducted in the presence of an alkali.
