Abstract

Disclosed are pour point depressants used in compositions and methods for achieving the cold flow properties of synthetic feedstock derived from plastic.

Claims10

Dependent claims

A method of improving the cold flow properties of a plastic-derived synthetic feedstock composition comprising:

adding a pour point depressant to a plastic-derived synthetic feedstock composition, wherein the pour point depressant comprises an ethylene vinyl acetate copolymer and an, alpha olefin maleic anhydride polymers.

Dependencies are inferred from the claim text.
