Sourcing commodity polymers from sustainable alternative feedstocks, such as those derived plastic waste or biobased resources, is a promising approach to alleviate the reliance on finite fossil fuel stocks for production of virgin plastics. Linear aliphatic dicarboxylic acids multiple chain lengths can be obtained polyethylene (PE) waste, and their use in synthesis polyesters has recently been demonstrated. To improve materials' properties chain-length dicarboxylates, we herein combined this feedstock with terephthalate an aromatic monomer unit yield aliphatic-aromatic copolyesters. We established structure-property relationships copolyesters dicarboxylates (C4-C20) model catalytic oxidation products PE 1,18-octadecanedioate reference materials single, long length dicarboxylates. Thermal solid-state structures were dominated by ratio units rather than identity dicarboxylate diol components. demonstrated upscaling copolyester synthesis, well processability mechanical copolyester, which showed comparable commercial polybutylene adipate-co-terephthalate. Finally, via transesterification thus postmodification premade polyesters, including postconsumer terephthalate, sources.
