Thermoreversible Diels-Alder Cross-Linking of BHMF-Based Polyesters: Synthesis, Characterization and Rheology.

ABSTRACT: 2,5-Bis(hydroxymethyl)furan (BHMF)-based polyesters are an interesting new class of biobased and potentially biodegradable furanic polymers. However, their thermal properties are currently insufficient, making them unsuitable for potential applications as commodity plastics. To improve this, several polyesters were synthesized using an enzymatic bulk polymerization process with the monomers BHMF and aliphatic dimethyl esters of varying spacer lengths. The BHMF units were subsequently cross-linked with a biobased bismaleimide (BM-689) through a [4 + 2] cycloaddition reaction between the furan and maleimide groups. This approach clearly demonstrated that these furan-based polyesters can be thermoreversibly cross-linked using this bismaleimide. The use of different spacer lengths further allo
