Aliphatic-Aromatic Copolyesters with Waste-Sourceable Multiple Chain-Length Building Blocks.

ABSTRACT: Sourcing commodity polymers from sustainable alternative feedstocks, such as those derived from plastic waste or biobased resources, is a promising approach to alleviate the reliance on finite fossil fuel stocks for the production of virgin plastics. Linear aliphatic dicarboxylic acids of multiple chain lengths can be obtained from polyethylene (PE) waste, and their use in the synthesis of aliphatic polyesters has recently been demonstrated. To improve the materials' properties of polyesters derived from multiple chain-length dicarboxylates, we herein combined this feedstock with terephthalate as an aromatic monomer unit to yield aliphatic-aromatic copolyesters. We established structure-property relationships for copolyesters derived from aliphatic dicarboxylates of multiple chain lengths
