PURPOSE:The titled resin composition suitable for electrical cables, protecting covers for cable connecting parts, etc., showing no reduction in flame retardance even by immersion in an acidic aqueous solution, obtained by blending a polar group-containing olefin polymer (mixture) with an inorganic hydrate. CONSTITUTION:(A) 100pts.wt. polar group-containing olefin polymer such as silane modified olefin polymer, olefin polymer grafted or copolymerized with an unsaturated carboxylic acid or its acid anhydride or a mixture of the polymer and another olefin polymer is blended with (B) 40-150pts.wt. inorganic hydrate such as aluminum hydroxide, magnesium hydroxide, calcium hydroxide or their mixture and, if necessary, carbon black, phosphorus, etc., to give an acid-resistant flame-retardant resin composition having strong bond between the components A and B and a small amount of elution of the component B even in the case of immersion in an acidic aqueous solution.
