It is expected to find a wide range of uses as it has the good properties of vinyl chloride resin (hereinafter referred to as PVC) and has improved heat resistance, which is a drawback of PVC. That is, cpvc is P
Like VC, it has excellent weather resistance, fire resistance, and chemical resistance, and its heat distortion temperature is 20 to 40°C higher than PVC, so it is being developed for a wider range of uses than PVC.

いう欠点もある。However, CPVC generally has a drawback in that it is difficult to mold due to its low thermal stability (initial coloration and heat resistance stability). As a means to improve this,
Method of adding polyhydroxycarboxylic acid to CPVC (
Unexamined Japanese Patent Publication 1986. -250047), method of adding nitrilotriacetic acid (JP-A-64-6002), method of adding diethylenetriaminepentaacetic acid (JP-A-1-131212)
Although these methods have the effect of improving initial coloring property, the effect is not sufficient, and the effect of improving heat resistance stability is hardly observed. On the other hand, the polymerization conversion rate was 4
It is also known that CPVC in which 0 to 70% of weight c is chlorinated has high thermal stability (Japanese Patent Application Laid-Open No. 58-103
507), its thermal stability is also insufficient, and if the polymerization conversion rate is lowered to increase thermal stability, it also has the disadvantage that polymerization productivity decreases.

Among these, calcium stearate and magnesium stearate are particularly preferred from the viewpoint of improving thermal stability and cost. The amount of these divalent or higher valent metal salts of fatty acids used is 0.000 parts by weight per 100 parts by weight of CPVC.
0.005 to 0.5 parts by weight, preferably 0.01 to 0.1 parts by weight. If the amount used is less than 0.005 parts by weight, the effect of improving thermal stability will be small, and if it exceeds 0.5 parts by weight, transparency will decrease.

These sheets were stacked and pressed at 195°C for 10 minutes to obtain a press plate with a thickness of 3 cylinders. The initial colorability and transparency of this press plate were evaluated by the b value and haze of a color difference meter (manufactured by Nihon Heavy Industries Ltd.).

５重量部が好ましいことが判る。From Table 2, it can be seen that calcium stearate and magnesium stearate improve both initial coloration and ml heat stability. Further, the amount of the divalent or higher J2 metal salt of fatty acid used is 0.005 to 0.5 parts by weight, particularly 0.01 to 0.5 parts by weight.
It turns out that 5 parts by weight is preferred.
本発明の組成物は、脂肪酸の２価以ヒの金属塩を含有し
２ていることに特徴がある。脂肪酸の２価基−にの金属
塩を含有させることにより初期着色性、耐熱安定性及び
透明性及び熱安定性をバランスよく備えたｃｐｖｃ成形
体が得られるのでかかる物性が要求される用途に適し、
その工業的な価値は極めて高い。The composition of the present invention is characterized in that it contains a divalent or higher metal salt of a fatty acid. By incorporating a metal salt into the divalent group of a fatty acid, a CPVC molded product with a well-balanced initial coloring property, heat resistance stability, transparency, and heat stability can be obtained, making it suitable for applications that require such physical properties. ,
Its industrial value is extremely high.
