法が行なわれているが、塩素化度が高くなると熔融粘度
が高くなり成形性が悪（なるという欠点があった。又、
塩化ビニル系樹脂に他の合成樹脂を添加する方法も種々
提案されている（たとえばポリ酢酸ビニルを添加するこ
とが特開昭６０−７９０５２号公報に記載されている。(Prior Art) Vinyl chloride resins have been widely used in molded products, films, sheets, etc., but they have the disadvantage of poor heat resistance. For this reason, a method of post-chlorinating vinyl chloride resin has been used, but as the degree of chlorination increases, the melt viscosity increases and moldability deteriorates.Also,
Various methods have also been proposed for adding other synthetic resins to vinyl chloride resins (for example, Japanese Patent Application Laid-Open No. 79052/1983 describes the addition of polyvinyl acetate).

とにある。(Problems to be Solved by the Invention) In view of the above-mentioned drawbacks, an object of the present invention is to provide a polyvinyl chloride-based molded product that has good thermal fluidity, excellent moldability, and can obtain molded products with excellent heat resistance and impact resistance. An object of the present invention is to provide a resin composition.

。(Means for Solving the Problems) The vinyl chloride resin used in the present invention refers to vinyl chloride resin, vinyl chloride, and monomers having ethylenically unsaturated bonds such as ethylene and propylene that can be copolymerized with vinyl chloride. and post-chlorinated products of these resins.
塩化ビニル系樹脂の平均重合度は、小さくなると得られ
た成形体の耐衝撃性が低下し、大きくなると熱流動性が
低下するので３００〜１４００が好ましい。又、後塩素
化物も平均重合度が３００〜１．４００の塩化ビニル系
樹脂が後塩素化されたものが好ましい。The average degree of polymerization of the vinyl chloride resin is preferably from 300 to 1,400 because as it becomes smaller, the impact resistance of the obtained molded article decreases, and as it increases, its thermal fluidity decreases. Also, the post-chlorinated product is preferably a post-chlorinated vinyl chloride resin having an average degree of polymerization of 300 to 1.400.
塩化ビニル系樹脂の平均塩素含有量は、少なくなると耐
熱性が低下し、逆に多くなると熱流動性が低下し、熱分

化ビニル系樹脂は、塩素含有量がこの範囲にはいるよう
に単独もしくは二種以上の樹脂が併用して使用されるの
が好ましい。The average chlorine content of the vinyl chloride resin is preferably 57 to 70 wt%, more preferably 62 wt%, since heat resistance decreases when it decreases, and conversely, thermal fluidity decreases when it increases, making it easier to thermally decompose. ~66 wt%. Therefore, the vinyl chloride resin is preferably used alone or in combination of two or more resins so that the chlorine content falls within this range.

ビニル系樹脂１００重量部に対し、２〜１５重量部添加
されるのであり、好ましくは３〜１０重量部である。If the amount of bisphenol S added is too small, thermal fluidity will not be improved and moldability will not be improved.On the other hand, if it is too large, the slipperiness during molding will become too strong and molding will become impossible. It is added in an amount of 2 to 15 parts by weight, preferably 3 to 10 parts by weight.
