Abstract

The present invention provides a liquid stabilizer that can provide a formed article excellent in both of transparency and heat resistance, and that is useful as a tin-free stabilizer. The present invention also provides a chlorine-containing resin composition using this stabilizer and a formed body using this stabilizer. The present invention is a liquid stabilizer for a chlorine-containing resin, comprising a zinc toluate and an overbased barium salt, wherein the content of the zinc toluate and the content of the overbased barium salt are 1 to 50% by mass and 50 to 99% by mass, respectively, based on a total amount of the zinc toluate and the overbased barium salt of 100% by mass.

First claim

The invention claimed is:

1. A liquid stabilizer for a chlorine-containing resin, comprising
a zinc m-toluate and an overbased barium salt,
wherein a content of the zinc m-toluate and a content of the overbased barium salt are 1 to 35% by mass and 65 to 99% by mass, respectively, based on a total amount of the zinc m-toluate and the overbased barium salt, which is 100% by mass.

2. A chlorine-containing resin composition, comprising
the liquid stabilizer for a chlorine-containing resin according to claim 1 and a chlorine-containing resin,
wherein a content of the liquid stabilizer as the total amount of the zinc m-toluate and the overbased barium salt is from 0.1 to 10 parts by mass per 100 parts by mass of the chlorine-containing resin.

3. The chlorine-containing resin composition according to claim 2 , further comprising
a plasticizer in an amount of greater than 0 parts by mass and 50 parts by mass or less per 100 parts by mass of the chlorine-containing resin.

4. The chlorine-containing resin composition according to claim 3 ,
wherein the plasticizer is at least one selected from the group consisting of a phthalic acid ester, an adipic acid alkyl ester, a non-phthalic acid plasticizer, and an epoxidized vegetable oil.

5. A formed body, prepared by using the chlorine-containing resin composition according to claim 2 .

6. The formed body according to claim 5 ,
wherein the formed body is a transparent formed body.

7. The formed body according to claim 5 ,
wherein the formed body is plate shaped, film shaped, or sheet shaped.
