Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a composition for improving, especially, the viscosity of a polyvinyl halide resin by incorporating an impact resistance modifier, a mineral oil, and optionally a specified amount of a plastic resin into the same. SOLUTION: This composition contains at least one impact resistance modifier selected from among methyl methacrylate-butadiene-styrene copolymers and acrylic impact resistance modifiers, a mineral oil preferably being a heavy mineral oil and/or a light mineral oil, and optionally at least one plastic resin in an amount of 50 wt.% or lower. The ratio of the mineral oil to the impact resistance modifier is preferably (0.1/10)-(4/10). The plastic resin is preferably selected from among polyvinyl halide polymers, polyalkylene terephthalate polymers, polycarbonate polymers, polyalkylene terephthalate-polycarbonate polymer blends, acrylonitrile-butadiene-styrene copolymers, polyolefin polymers, etc.
