PURPOSE:To obtain a crosslinked foamable resin composition suitable for a boot sole material and a heat-insulating material, etc., having steeply improved moldability with reducing tackiness to a metal by mixing a specific amount of a rubbery material containing a polar group in an ionomer resin. CONSTITUTION:(A) 100 pts.wt. partially metallic salt of an ethylene-unsaturated carboxylic acid copolymer having 0.1-500 MFR is mixed with (B) 30-300 pts.wt., preferably 50-200 pts.wt. synthetic rubber containing a polar group (e.g. acrylonitrile/butadiene copolymer rubber), (C) a chemical crosslinking agent (e.g. dicumyl peroxide) in an amount of 0.1-5 pts.wt. to total 100 pts.wt. of the components A and B and (D) a chemical foaming agent (e.g. azodicalboxylic amide) in an amount of 0.1-20 pts.wt., preferably 0.5-10 pts.wt. to total 100 pts.wt. of the components A and B. |
