Sustainable Chain Extenders for Recycling Polyesters

Executive Summary Polyesters comprise a significant portion of plastics entering landfills. One issue that limits their recycling is degradation during melt processing which lowers their molecular weight and melt viscosity. Reactive chain extenders are often used in this case to build back the molecular weight of the polyester during reprocessing....
