    Abstract: The invention relates to bio-based polymer based on at least two different bio-based monomers obtained from biomass-containing carbohydrates, wherein at least one bio-based monomer is a furan derivative according to formula (I). In each case, independently of one another, R1 is a hydrogen or an organofunctional group with 1 to 20 C atoms and optionally, the organofunctional group contains O, N, or S atoms; R2 is an organofunctional group with 1 to 20 C atoms, which optionally contains O, N, or S atoms, the second bio-based monomer is a hydroxyl-functional compound comprising from 1 to 100 C atoms. The polymer has an average molecular weight Mw greater than or equal to 1,000 g/mol, and the proportion of bio-based monomers in the bio-based polymer is greater than or equal to 55 mol-% with respect to all monomers of the polymer.

    Abstract: There is provided a method of preparation for a biodegradable co-polyester, the method including: forming an oligomer through a primary esterification reaction between a hydroxy group of an aliphatic dihydroxy compound and a carboxylic group of an aliphatic dicarboxylic acid compound; performing a secondary esterification reaction between the formed oligomer and an aromatic dicarboxylic acid compound; and performing a polycondensation reaction in a vacuum, in which sequentially divided addition of the aromatic dicarboxylic acid compound is performed and the weight ratio of the aromatic dicarboxylic acid compound with respect to the oligomer for each time of the sequentially divided addition is from 2:8 to 5:5. The method efficiently increases a solubility of aromatic dicarboxylic acid, thereby increasing a reaction rate and reducing a side reaction.
