Abstract (en)
[origin: WO2021254892A1] The present invention relates to a process for preparing a polyester carbonate on the basis of cycloaliphatic diacids and at least one 1,4:3,6-dianhydrohexitol and at least one further aliphatic dihydroxy compound, to the polyester carbonate prepared according to the process and to a molding compound and a molded product containing the polyester carbonate. The process according to the invention is a direct synthesis, in which all structural elements forming the subsequent polyester carbonate are present as monomers already in the first process step.
