Claim 11:
12. A method of improving processing ability of a thermoplastic resin, the method comprising:
adding from 0.1 to 30 parts by weight of at least one processing aid to 100 parts by weight of at least one thermoplastic resin,
wherein the at least one processing aid has a styrene-equivalent weight average molecular weight of from 300,000 to 8,000,000, and
wherein the at least one processing aid comprises at least 60 wt % of a polymer obtained by polymerizing monomers comprising from 40 to 99.9 wt % of styrene, from 1 to 7 wt % of at least one acid group-containing monomer, and from 0 to 59.9 wt % of at least one vinyl monomer.
