Patent ID: 6946520

Claim:
A fabricated article prepared from a blend comprising: A. from 30 to 93 weight percent of one or more homopolymers or copolymers and B. from 5 to 70 weight percent of at least one substantially random interpolymer; wherein said substantially random interpolymer comprises monomer units derived from (a) about 1.5 to 15 mol percent of vinyl aromatic monomer; (b) about 3 to 50 mol percent of propylene; and (c) the balance being ethylene; C. from 0 to 50 weight percent of one or more polymer selected from styrenic homopolymers and copolymers, including random styrene/diene copolymers and hydrogenated random styrene butadiene copolymer, ethylene homopolymers and copolymers, including ethylene/styrene interpolymers, and styrenic block copolymers, and D. from 0 to 80 weight percent of one or more fillers, wherein the fabricated article is in the form of a film, a sheet or as a layer in a multi-layer film structure, wherein the absolute difference between the refractive index of said polypropylene homopolymer or copolymer and the refractive index of said substantially random interpolymer is less than or equal to 0.020; and with the proviso that the fabricated article is free of conductive additives.
