The detailed structure analysis of these polycarbonates has been confirmed by a series of 2D NMR (HSQC and COSY) characterizations. Depending on the stereoisomerism of MBC, the PC-MBC displayed a wide achievable <i>T</i> _g range of 117-174 °C and high <i>T</i> _d5% of >310 °C by variation of the ratio of the stereoisomers of MBC, offering great substitution perspectives towards a bisphenol-containing polycarbonates. Nonetheless, the most here presented PC-MBC polycarbonates were film-forming and transparent.Polymer chemistryNovel stereoisomeric lignin-derived polycarbonates: towards the creation of bisphenol polycarbonate mimics.PMC9942097grant number 201808330391201808330391875649ERC Proof of Concept Grant 2019 (PURE) 875649638076ERC Starting Grant 2015 (CatASus) 638076723.015.005Trimmel GBarta KXu DDe Bruyn MWu XfalseNovel stereoisomeric lignin-derived polycarbonates: towards the creation of bisphenol polycarbonate mimics.In this work, we have described a family of bio-based polycarbonates (PC-MBC) based on the unique lignin-derived aliphatic diol 4,4'-methylenebiscyclohexanol (MBC) that was sustainably sourced from lignin oxidation mixture.
