  The present disclosure provides recombinant microorganisms and methods for the production of 4-HMF, 2,4-furandimethanol, furan-2,4-dicarbaldehyde, 4-(hydroxymethyl)furoic acid, 2-formylfuran-4-carboxylate, 4-formylfuran-2-carboxylate, and/or 2,4-FDCA from a carbon source. The method provides for engineered microorganisms that express endogenous and/or exogenous nucleic acid molecules that catalyze the conversion of a carbon source into 4-HMF, 2,4-furandimethanol, furan-2,4-dicarbaldehyde, 4-(hydroxymethyl)furoic acid, 2-formylfuran-4-carboxylate, 4-formylfuran-2-carboxylate, and/or 2,4-FDCA. The disclosure further provides methods of producing polymers derived from 4-HMF, 2,4-furandimethanol, furan-2,4-dicarbaldehyde, 4-(hydroxymethyl)furoic acid, 2-formylfuran-4-carboxylate, 4-formylfuran-2-carboxylate, and/or 2,4-FDCA.

  The present invention generally relates to covalent network polymers prepared from an imine-linked oligomer and an independent crosslinker comprising reactive moieties selected from the group consisting of epoxy, isocyanate, bismaleimide, sulfide, polyurethane, anhydride, polyester and combinations thereof. The covalent network polymers disclosed herein are advantageously made by anhydrous reactions, which enables the highest known glass transition temperatures to date for this class of materials. Further, the disclosed covalent network polymers can be formed in continuous processes, such as additive manufacturing processes that produce three-dimensional objects or roll-to-roll processes that produce covalent network polymer films or fully cured prepreg in various size formats.

  本发明一般涉及由亚胺连接的低聚物和独立交联剂制备的共价网络聚合物，独立交联剂包含选自环氧、异氰酸酯、双马来酰亚胺、硫化物、聚氨酯、酸酐、聚酯及其组合的反应分子。本文所公开的共价网络聚合物是通过无水反应制成的，这使得该类材料的玻璃化转变温度达到了目前已知的最高值。此外，所公开的共价网络聚合物可在连续工艺中形成，例如可生产三维物体的增材制造工艺或可生产各种规格共价网络聚合物薄膜或完全固化预浸料的卷对卷工艺。
