Increasing the solubility range of polyesters by tuning their microstructure with co-monomers
Research output: Contribution to conference › Abstract › Academic
It was attempted to break the crystallinity of PDL-based co-polyesters with a view of increasing their solubility range. Therefore, PDL was copolymerized with the branched and biobased δ-undecalactone (UDL), whose homopolymer is amorphous. In order to obtain random microstructure rather than block-like, several monomer addition strategies were investigated. Monomer distribution within the PDL-co-UDL polyesters was assessed by 13C NMR. It was observed that crystallinity of the co-polyesters was decreased but not suppressed as measured by DSC, partially because they did not display a fully random monomer order. Hansen solubility parameters determination however showed that the solubility range of the co-polyesters was improved compared to PDL homopolymers.
