A blend of polymeric materials comprising n (A) of from about 1 to about 99.99 weight percent based on the combined weights of Components A, B and C of at least one substantially random interpolymer; and wherein said interpolymer; n (1) contains of from about 0.5 to about 65 mole percent of polymer units derived from; n (a) at least one vinyl or vinylidene aromatic monomer, or n (b) at least one hindered aliphatic or cycloaliphatic vinyl or vinylidene monomer, or n (c) a combination of at least one vinyl or vinylidene aromatic monomer and at least one hindered aliphatic or cycloaliphatic vinyl or vinylidene monomer; n (2) contains of from about 35 to about 99.5 mole percent of polymer units derived from at least one aliphatic α-olefin having from 2 to 20 carbon atoms; n (3) has a molecular weight (Mn) greater than about 1,000; n (4) has a melt index (I 2 ) of from about 0.01 to about 1,000; n (5) has a molecular weight distribution (M w /M n ) of from about 1.5 to about 20; and n (B) of from about 99 to about 0.01 weight percent based on the combined weights of Components A, B, and C of one or more conductive additives and/or one or more additives with high magnetic permeability; and n (C) of from 0 to about 98.99 weight percent based on the combined weights of Components A, B, and C of one or more polymers other than A. |
