ABSTRACT:
Vinyl halide resin compositions having improved fire resistance are formed by the introduction into said compositions of a small amount of a reactive hydroxy group-containing polyvalent metal salt of a phenol-aldehyde resin of the novolac type. The resulting vinyl halide resins evidence increase charring of the surface when exposed to heating by a flame or undergoing combustion, the surface char acting as a barrier to heat transfer from the flame and retarding the flow of volatile gases from the pyrolyzing resin.
