COMPOSITIONS OF INTERPOLYMERS OF ALPHA-OLEFIN MONOMERS WITH ONE OR MORE VINYL OR VINYLIDENE AROMATIC MONOMERS

摘要

A blend of polymeric materials comprising: (A) from 1 to 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: (1) contains from 0.5 to 65 mole 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 vinyl or vinylidene aromatic monomer and at least one hindered aliphatic or cycloaliphatic vinyl or vinylidene monomer; (2) contains from 35 to 99.5 mole percent of polymer units derived from at least one aliphatic .alpha.-olefin having from 2 to 20 carbon atoms; (3) has a molecular weight (Mn) greater than 1,000; (4) has a melt index (I2) from 0.01 to 1,000; (5) has a molecular weight distribution (Mw/Mn) from 1.5 to 20; and (B) from 99 to 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 (C) from 0 to 98.99 weight percent based on the combined weights of Components A, B, and C of one or more polymers other than A.
