本発明は耐熱性のすぐれた塩素化塩化ビニル樹脂組成物
に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a chlorinated vinyl chloride resin composition with excellent heat resistance.
従来より、塩化ビニル系樹脂は広範に使用されているが
、耐熱性が悪いという欠点を有していた。この欠点を解
消するために塩化ビニル系樹脂とポリカーボネート樹脂
をブレンドすること（特公昭５７−１５６１３号公報）
が試みられているが、塩化ビニル系樹脂とポリカーボネ

った。このため両者の相溶化剤としてＡＢＳ樹脂、スチ
レン−無水マレイン酸共重合体、エチレン−酢酸ビニル
共重合体（特開昭４９−１０７３５６号公報）、ゴムに
ビニル化合物をグラフトさせたグラフト重合体（特公昭
５７−９３９０号公報）等が提案されているが、依然と
して相溶性が不充分で耐熱性はあまり向上しなかった。Conventionally, vinyl chloride resins have been widely used, but they have had the disadvantage of poor heat resistance. In order to eliminate this drawback, vinyl chloride resin and polycarbonate resin are blended (Japanese Patent Publication No. 15613/1983).
However, the compatibility between vinyl chloride resin and polycarbonate resin was poor, and the heat resistance did not improve much. Therefore, as compatibilizing agents for both, ABS resin, styrene-maleic anhydride copolymer, ethylene-vinyl acetate copolymer (Japanese Patent Application Laid-open No. 107356/1982), and a graft polymer in which a vinyl compound is grafted onto rubber ( Japanese Patent Publication No. 57-9390) and the like have been proposed, but the compatibility is still insufficient and the heat resistance has not improved much.
本発明の目的は、上記欠点に鑑み、塩化ビニル樹脂より
も耐熱性のすぐれた塩素化塩化ビニル樹脂とポリカーボ
ネート樹脂を使用し、成形性がよく、耐熱性及び耐衝撃
性がすぐれた成形体を得ることができる塩素化塩化ビニ
ル樹脂組成物を提供することにある。In view of the above-mentioned drawbacks, the object of the present invention is to produce a molded article with good moldability, excellent heat resistance and impact resistance by using chlorinated vinyl chloride resin and polycarbonate resin which have better heat resistance than vinyl chloride resin. An object of the present invention is to provide a chlorinated vinyl chloride resin composition that can be obtained.
本発明で用いる塩素化塩化ビニル樹脂としては、塩素化
度は大きくなると熱分解しやすくなるので６２〜７０％
が好ましく、又重合度は小さくなると機械的強度が低下
し、太き（なると成形性が低下するので５００〜１５０
０が好ましい。尚、塩素化塩化ビニル樹脂として一部塩
化ビニル樹脂を使用してもよい。The degree of chlorination of the chlorinated vinyl chloride resin used in the present invention is 62 to 70%, since the higher the degree of chlorination, the easier it is to thermally decompose.
It is preferable that the degree of polymerization is 500 to 150, since the mechanical strength decreases as the degree of polymerization decreases, and the moldability decreases as the degree of polymerization decreases.
0 is preferred. Note that vinyl chloride resin may be used in part as the chlorinated vinyl chloride resin.
本発明で用いるポリカーボネート樹脂としては、従来公
知のものが使用できるが分子量が大きくなると相溶性が
低下し、逆に分子量が小さくなると耐熱性を付与する効
果がなくなるので、分子量は１．５００〜２５．０００
が好ましく、より好ましくは２．５００〜１８．０００
である。Conventionally known polycarbonate resins can be used as the polycarbonate resin used in the present invention, but as the molecular weight increases, the compatibility decreases, and conversely, as the molecular weight decreases, the effect of imparting heat resistance is lost, so the molecular weight is 1.500 to 25. .000
is preferable, more preferably 2.500 to 18.000
It is.
ポリカーボネート樹脂は塩素化塩化ビニル樹脂１００重
量部に対し、１〜１００重量部添加されるが、添加量が
少ないと耐熱性を向上させる効果がなくなり、逆に多く
なると耐衝撃性等の力学特性が低下するので１０〜４０
重量部添加されるのが好ましい。Polycarbonate resin is added in an amount of 1 to 100 parts by weight per 100 parts by weight of chlorinated vinyl chloride resin, but if the amount added is small, it will not have the effect of improving heat resistance, and if it is too large, the mechanical properties such as impact resistance will deteriorate. 10-40 as it decreases
Preferably, it is added in parts by weight.

エチルメタクリレート、ポリｎ−プロビルメタクリレー
ト、ポリｎ−ブチルメタクリレート及びポリ酢酸ビニル
の中から選ばれた一種以上の樹脂からなるものである。The diblock copolymer used in the present invention acts as a compatibilizer for chlorinated vinyl chloride resin and polycarbonate resin, and one block is composed of polystyrene, styrene-acrylonitrile copolymer, and styrene-maleic anhydride copolymer. The other block is made of one or more resins selected from the group consisting of one or more resins selected from polymethyl methacrylate, polyethyl methacrylate, poly n-propyl methacrylate, poly n-butyl methacrylate, and polyvinyl acetate. It is made of resin.
尚、上記スチレン−アクリロニトリル共重合体及びスチ

ブロックの樹脂の分子量は他方のブロックの樹脂の分子
量の１／１０〜１０倍が好ましく、より好ましくは路間
−である。Also, if the difference in molecular weight between the resins in one block and the other block becomes large, the compatibilization effect will decrease, so the molecular weight of the resin in one block should be 1/10 to 10 times that of the resin in the other block. Preferably, and more preferably between roads.
ジブロック共重合体の分子量は小さすぎると耐熱性が低
下し、大きすぎると成形性が低下するので、１０００以
上が好ましく、より好ましくは１０．０００〜５００．
０００である。If the molecular weight of the diblock copolymer is too small, the heat resistance will decrease, and if it is too large, the moldability will decrease, so it is preferably 1000 or more, more preferably 10.000 to 500.
It is 000.

重量部である。When the amount of diblock copolymer added is small, the compatibilizing effect decreases, and conversely, when the amount of diblock copolymer added is small, the compatibilizing effect becomes constant from a certain point and the mechanical properties decrease.
0.1 to 3 per 100 parts by weight of chlorinated vinyl chloride resin
0 parts by weight is added, preferably 0.5 to 10 parts by weight.
