ABSTRACT:
A electrical conductivity modified thermoplastic olefin (TPO) polymer blend with improved electrostatic painting efficiency, the blend comprising a substantially uniform mixture of: I. polymeric material being the reaction product of: (a) polypropylene, (b) maleated polypropylene, (c) elastomer, and (d) amine-terminated polyether being a linear or branched polymer of oxypropyleneamine or oxyethyleneamine repeating units having 40-100 such units, and II. alkali metal salt, the alkali metal salt being included in the thermoplastic polymer blend in an amount which provides the blend with a conductivity of at least 10.sup.-12 S/cm at 25.degree. C.
