れていた。However, the surface of these transparent molded products becomes white and opaque when they are used for packaging products such as water, alcohol, and aqueous alcohol solutions, or when they are left in a hot and humid atmosphere for a long time. However, there is a problem in that the value of the molded product is significantly impaired, and an effective countermeasure for it has been desired.

旨とするものである。(Means for Solving Problems) The present invention has been achieved as a result of intensive research to solve this problem. The saponification degree is 20 to 55 mol% and the average degree of polymerization is 100 parts by weight of vinyl chloride resin. It is a gist of the present invention to provide a vinyl chloride-based resin composition having a transparent whitening amount of 150 to 600 partially saponified polyvinyl alcohol in an amount of 0.01 to 5 parts by weight and less whitening.

で用いても、２成分以上を併用してもよい。Explaining this, the main component of the vinyl chloride resin composition of the present invention is a polymer of vinyl chloride alone, a copolymer of vinyl chloride containing 50% by weight or more of vinyl chloride and various other vinyl monomers. A polymer or a polymer blend of at least one of these copolymers and an impact resistance enhancer for vinyl chloride resin, which has a vinyl chloride content of 50% by weight or more and is copolymerized with vinyl chloride. Other components include acrylic acid, methacrylic acid, maleic anhydride or their esters, vinylidene chloride, vinyl acetate, alkyl vinyl ethers, alkyl vinyl ketones,
Examples thereof include ethylene, propylene, and various other known vinyl monomers, and examples of the impact resistant reinforcing agent for vinyl chloride resin include ABS resin and MBS resin. These may be used alone or in combination of two or more components.

ることにより達成される。The whitening-preventing effect of the transparent molded article according to the present invention is achieved by adding 0.01 to 5% by weight of partially saponified polyvinyl alcohol having a saponification degree of 20 to 55 mol% and an average degree of polymerization of 150 to 600 to this polymer component.
これが0.01％未満では成形品の白化防止の効果が充分で
なく、また５％を超えると量の増加の割合には白化防止
の効果が向上せず経済的でなくなる。If it is less than 0.01%, the effect of preventing whitening of the molded article is not sufficient, and if it exceeds 5%, the effect of preventing whitening does not improve in proportion to the increase of the amount, which is not economical.
この配合時の形態は粉体状、液状など特に制限は無い。The form at the time of this mixing is not particularly limited, such as powder and liquid.
