  • Polyesters based on 2-methylsuccinic acid
    Patent number: 8546472
    Abstract: The present invention relates to a polyester comprising repeat units based on at least one aliphatic dicarboxylic acid or an ester-forming derivative thereof (component A1), at least one aromatic dicarboxylic acid or an ester-forming derivative thereof (component A2), at least one diol (component B), optionally at least one sulfo-containing compound (component A3) and optionally at least one trifunctional crosslinking agent as component C1 and/or at least one difunctional chain extender as component C2, component A1 comprising 2-methylsuccinic acid or an ester-forming derivative thereof, to a process for preparing the inventive polyester, to the mixtures comprising the inventive polyester, to the use of the inventive polyesters or of the inventive mixtures for production of moldings, films, adhesives, foams or fibers, and to moldings, films, adhesives, foams or fibers comprising at least one inventive polyester or at least one inventive mixture.
