| 摘要 |
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. |
