The present invention relates to a blend comprising at least one interpolymer produced from polymerizing a monomer mixture comprising from about 5 to about 65 mole percent of (a) at least one vinylidene aromatic monomer, or (b) a combination of at least one vinylidene aromatic monomer and at least one hindered aliphatic vinylidene monomer, and from about 35 to about 95 mole percent of at least one aliphatic &agr;-olefin having from about 2 to about 20 carbon atoms; and a composition comprising an aromatic polyether and optionally (a) at least one homopolymer of a vinylidene aromatic monomer, or (b) at least one interpolymer of one or more vinylidene aromatic monomers, or (c) at least one interpolymer of at least one vinylidene aromatic monomer and at least one hindered aliphatic vinylidene monomers, or (d) at least one of (a-c) further comprising an impact modifier, or (e) a combination of any two or more of the aromatic polyether and (a-d). The blend also comprises at least one optional impact modifier and at least one optional processing aid. The blend is useful in the preparation of fabricated articles such as adhesives, films, blow molded articles, and injection molded articles, and is characterized by improved high temperature serviceability.
