Compatibilized blends of alkenyl aromatic polymers, α-olefin/vinyl or vinylidene aromatic and/or sterically hindered aliphatic or cycloaliphatic vinyl or vinylidene interpolymers and styrenic block copolymers

An injection molded article having a paintability score of 5 (according to ASTM Method D-3359), prepared from a blend composition comprising;

• (A) one or more alkenyl aromatic polymers;
• (B) one or more substantially random interpolymers comprising
• (1) from about 0.5 to about 15 mol percent of polymer units derived from;
• (a) at least one vinyl or vinylidene aromatic monomer, or
• (b) at least one hindered aliphatic or cycloaliphatic vinyl or vinylidene monomer, or
• (c) a combination of at least one aromatic vinyl or vinylidene monomer and at least one hindered aliphatic or cycloaliphatic vinyl or vinylidene monomer, and
• (2)) from about 85 to about 99.5 mol percent of polymer units derived from at least one of ethylene and/or a C3-20 α-olefin;
• and
• (3)) from 0 to about 20 mol percent of polymer units derived from one or more of ethylenically unsaturated polymerizable monomers other than those derived from (1) and (2);
• and,
• (C) one or more compatibilizers;
• and wherein said blend has;
