Abstract: Disclosed herein are bio-derivable polyhydroxyurethanes, methods of making them, compositions comprising the same, and articles comprising such compositions. The bio-derivable polyhydroxyurethane comprises in polymerized form at least one polymerizable lignin-derivable cyclic carbonate monomer, and one or more polymerizable amine crosslinkers, each comprising two or more primary amines, such that at least one of the one or more polymerizable amine crosslinkers comprises three primary amines. The bio-derivable polyhydroxyurethanes display enhanced mechanical performance as compared to the petroleum-derived analogues.

Abstract: Disclosed herein are bio-based polysulfones, and in particular, bisguaiacol-based PSfs synthesized from (i) at least one polymerizable lignin-based monomer having a structure corresponding to formula (I) wherein each R1 is independently either an H or a methyl group, wherein R2, R3, and R4 are each individually selected from an H or a methoxy group, and (ii) at least one polymerizable 4,4?-dihalophenyl sulfone as a comonomer.
