Abstract

Compositions comprising recyclate blends of polymer recyclate and polyester additives are described. In certain embodiments, the polyester additive is a PHA such as a poly-3-hydroxybutyrate-co-4-hydroxybutyrate copolymer having a weight percent 4-hydroxybutyrate of 8.5-45%. In other embodiments the PHA is mixed with the recyclate polymer at concentrations of 10-50% by weight of the recyclate blend. Methods of making the compositions of the invention are also described. The invention also includes articles made from the recyclate blends.
