POLYMER COMPOSITION, METHOD, AND ARTICLE

摘要

A synergistic flame retardant combination includes (a) a phosphorus salt having the Formula (I) wherein M<SUP>d+</SUP> is a metal ion or an onium ion; d is 1, 2, 3, or 4 according to the identity of M and its oxidation state; each occurrence of R<SUP>1</SUP> and R<SUP>2</SUP> is independently C<SUB>1</SUB>-C<SUB>18</SUB> hydrocarbyl; and each occurrence of m and n is independently 0 or 1 ; and (b) a phosphine compound selected from trihydrocarbylphosphines, trihydrocarbylphosphine oxides, and combinations thereof. Polymer compositions utilizing the flame retardant combination are described.
