Abstract
Vinyl halide resin compositions containing a metal compound stabilizer and coated acid absorber particles, where the coating consists of a tin-based coating or a complex calcium/zinc/strontium phosphate-based coating, are used to confer heat stability to such compositions. Use of the costabilizers of this invention results in economic advantages and material cost savings.
