PROBLEM TO BE SOLVED: To provide a vinyl chloride resin having excellent thermal stability and moldability as well as impact resistance. SOLUTION: The objective vinyl chloride resin is characterized by the graft copolymerization of (A) 1-30 wt.% acrylic copolymer having a glass transition temperature of <=-20 deg.C and produced by the soap-free polymerization of radically polymerizable monomers composed mainly of a (meth)acrylate and (B) 99-70 wt.% vinyl monomers composed mainly of vinyl chloride.
