Resin composition and molded body formed therefrom

A resin composition, comprising 3 to 15 parts by mass of rubber-based impact absorber (B) and 0.1 to 10 parts by mass of lubricant (C) with respect to 100 parts by mass of vinyl chloride-based resin (A), and satisfying the following requirements (I) to (III):

• (I) the vinyl chloride-based resin (A) has a chlorine content of 55 to 75 mass %;
• (II) the rubber-based impact absorber (B) has a glass transition temperature (Tg), measured by differential scanning calorimetry (DSC), of 0° C. or less;
• and
• (III) the lubricant (C) satisfies the following requirements (i) to (iv):
• (i) a melt viscosity at 200° C. is 5 to 5,000 mPa·s;
• (ii) a softening point is in a range of 60 to 180° C.;
• (iii) a glass transition temperature (Tg) measured with a differential scanning calorimeter (DSC) is in a range of 0 to 100° C.;
• and
• (iv) in a molecule, a structural unit derived from at least one selected from the group consisting of styrene, α-methylstyrene, indene, vinyltoluene, and isopropenyltoluene is contained in an amount of 50 to 100 mass %,
• wherein the resin composition is molded into a pipe joint.
