ABSTRACT:
Motor vehicle components are provided having an improved stability at moderate temperatures and shaped from polyvinyl chloride resin compositions, comprising a polyvinyl chloride resin, at least one heat stabilizer in a sufficient amount to impart heat processing stability, and a .beta.-diketone in a sufficient amount to provide, after forming, stability at moderate temperatures not provided by any residual heat stabilizer, as well as polyvinyl chloride resin stabilizer compositions and polyvinyl chloride resin compositions containing such heat stabilizer compositions suitable for use in forming motor vehicle components, comprising at least one heat stabilizer and a .beta.-diketone.
