Abstract
A smoke suppressed rigid or plasticized polyvinyl chloride polymer composition contains a polyvinyl chloride polymer and a small but effective amount of a smoke suppressant consisting essentially of a mixture of Zn.sub.3 Mo.sub.2 O.sub.9 .multidot.H.sub.2 O and ZnHPO.sub.3, in an atomic ratio of Mo to P of about 0.5:1 to about 2.0:1, to impart smoke suppression to the polymer composition.
