〔産業上の利用分野］
本発明は、ポリプロピレン樹脂組成物に関し、詳しくは
、臭気がなく透明性、成形性、耐衝撃性に優れたポリプ
ロピレン樹脂組成物に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a polypropylene resin composition, and more particularly to a polypropylene resin composition that is odorless and has excellent transparency, moldability, and impact resistance.
ポリプロピレン樹脂は、化学的・物理的性質に優れ、し
かも安価である等の点で広く用いられており、用途も工
業分野から食品、医療等の容器まで多岐にわたっている
。Polypropylene resin is widely used because it has excellent chemical and physical properties and is inexpensive, and its uses range from industrial fields to food, medical, and other containers.
しかし、ポリプロピレン樹脂は通常の成形方法では透明
性が悪いことから、ソルビトール系の造核剤を添加し透
明性の改良が行われて来た（特開昭５６−３０４４９、
同５６−３０４５０、同５６−４５９３４等）。However, since polypropylene resin has poor transparency when used with normal molding methods, the transparency has been improved by adding a sorbitol-based nucleating agent (Japanese Patent Laid-Open No. 56-30449,
56-30450, 56-45934, etc.).
しかしながら、ソルビトール系の造核剤を添加したポリ

ビトール系の造核剤にかえて、リン系の化合物を用いる
方法も提案されている（特公昭６３−８９８０等）。However, polypropylene resin to which a sorbitol-based nucleating agent has been added has a bad odor and its uses are limited, and there are problems in the field of food containers, for example. A method using a phosphorus-based compound instead of a sorbitol-based nucleating agent has also been proposed (Japanese Patent Publication No. 63-8980, etc.).
Ｃ本発明が解決しようとする問題点〕
上述のリン系の化合物を用いると、確かに、臭気は改良

撃性も低く、そのために用途が限られる等の問題があっ
た。C Problems to be Solved by the Present Invention] Although odor is certainly improved by using the above-mentioned phosphorus-based compound, the transparency of polypropylene resin is lower than that using a sorbitol-based nucleating agent. Depending on the type, it may be somewhat poor, and its moldability (drawdown) and impact resistance are also low, which limits its uses.
