| titleOfInvention | Process for the production of one or more polyester copolymers, method for the preparation of one or more oligomers, oligomer composition and polyester copolymer |
| abstract | A process for the production of one or more polyester copolymers, comprising the steps of: a) oligomerizing one or more, cyclic or bicyclic, diol monomers with a molar excess of one or more dicarboxylic monomers, which one or more dicarboxylic monomers comprise one or more oxalic monomers chosen from the group consisting of oxalic acid, oxalic monoesters and oxalic diesters, to yield one or more oligomers; and b) polymerizing the one or more oligomers with one or more primary diol monomers. A method for the preparation of one or more oligomers, which method comprises melt mixing one or more, cyclic or bicyclic, diol monomers with one or more oxalic monomers chosen from the group consisting of oxalic acid, oxalic monoesters and oxalic diesters, in a molar ratio of the one or more oxalic monomers to the one or more, cyclic or bicyclic, diol monomers of more than 1.1:1. An oligomer composition obtainable by such method and a polyester copolymer obtainable by such process. |
