Abstract
The polyvinyl chloride resin composition of the invention is highly heat-resistant as a result of compounding with an organic tin mercaptide compound as a heat stabilizer but is still free from the problem of the unpleasant odor emitted by the mercaptide compound owing to a specific deodorizing agent compounded therewith so that the composition is suitable as a molding resin composition for food containers. The above mentioned deodorizing agent is a diterpenic acid such as abietic acid or a rosin which is a crude mixture of several kinds of diterpenic acids obtained as a natural product.
