【産業上の利用分野】本発明は加工性がよく耐衝撃性に
優れた塩化ビニル系樹脂組成物に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vinyl chloride resin composition having good processability and excellent impact resistance.

で必要とされる流動性と表面平滑性に欠けてくる。2. Description of the Related Art In many vinyl chloride resins, generally, the higher the average degree of polymerization in a hard compound, the better the physical properties such as tensile strength and heat resistance, and the addition of an impact resistance modifier is very effective. It is known to be obtained. However, as the degree of polymerization increases, the workability decreases, and the fluidity and surface smoothness required for high-speed molding such as calendar molding, extrusion molding, injection molding and blow molding are lacking.
【０００３】このような流動性と表面平滑性の不足を補

な流動性と表面平滑性の得られる状態にまで温度条件を
高めると、樹脂そのものが熱によって劣化し、本来樹脂
が持っている筈の物性が発揮されなくなる。There is a method of increasing the processing temperature as a method of compensating for such a lack of fluidity and surface smoothness. However, when the average degree of polymerization of vinyl chloride resin is high in a hard compounding system, satisfactory fluidity and surface are obtained. If the temperature condition is raised to a state where smoothness is obtained, the resin itself will deteriorate due to heat, and the physical properties that the resin should have will not be exhibited.

の低い樹脂を用いると、流動性と表面平滑性は向上する
ものの耐衝撃性が低下するので、さらに多量の改質剤を

物性も低下する恐れがあった。If a resin having a low degree of polymerization is used to improve molding processability, fluidity and surface smoothness are improved but impact resistance is lowered. Therefore, a larger amount of modifier must be kneaded. As a result, physical properties such as heat resistance and tensile strength may be deteriorated.

の添加剤のため衝撃性も改善できると考えられてきた。For these reasons, a processing aid is added to improve the processability of the vinyl chloride resin, and a small amount of a rubber polymer is added as an impact modifier to improve the impact resistance. Has been generally adopted. It has been considered that this method improves the workability and fluidity under mild processing conditions, and the impact resistance can be improved because of the rubber-based additive.

A resin composition obtained by adding 1 to 10 parts by weight of at least one polymer of styrene (hereinafter referred to as ABS) copolymer resin and chlorinated polyethylene is described. Although the fluidity is improved, the fluidity and surface smoothness are not improved.

As a result of a thorough study, by adding ABS to vinyl chloride resin, impact resistance is improved, and by adding butadiene / styrene rubber (hereinafter referred to as SBR), fluidity and surface smoothness are improved, and acrylonitrile The inventors have found that the tensile strength can be improved by adding a styrene (hereinafter referred to as AS) copolymer, and have completed the present invention.
