    摘要： Branched polyesters with sulfonate groups can be obtained by reacting components A, B, optionally C, and optionally D to yield branched polyesters, then reacting these branched polyesters with hydrogen sulfite. Component A is at least one α,β-olefinically unsaturated dicarboxylic acid, component B is at least one di- or higher-functional alcohol, optional component C is at least one di- or higher-functional carboxylic acid or hydroxycarboxylic acid without an α,β-olefinically unsaturated bond, and optional component D is at least one compound of formula CH3(—O—CH2—CH2)n—OH. In reacting the branched polyesters with hydrogen sulfite, a molar amount of hydrogen sulfite is at most 95 mol %, based on an amount of α,β-olefinically unsaturated dicarboxylic acid.

    摘要： The present invention relates to a method for the recycling waste polyester resins and the reclaimed materials therefrom. The method for recycling waste polyester resins according to one embodiment the present invention comprises (a) depolymerizing waste polyester resin; (b) polycondensing the depolymerized product from step (a) with a polyhydric alcohol to provide a polyester polymer having an acid value of 10-150 mgKOH/g; and (c) recovering the polyester polymer in solid or liquid form if the polyester polymer from step (b) has an acid value of more than 20 mgKOH/g or recovering the polyester polymer in solid form if the polyester polymer from step (b) has an acid value of less than 20 mgkOH/g. The reclaimed polyester resin according to the present invention has the excellent compatibility, dispersibility, and adhesive property for various media, and can be used easily neutralized and dissolved in water. Accordingly, the polyester resin can be used as a useful material for industrial products.
