The incorporation of an alkaline earth hydroxide or oxide in a non-nitrogen-containing polymer results in the reduction of carbon monoxide and visible smoke generated during burning of the polymer. The polymer may be an elastomer, (that is a rubber), a thermoplastic, a thermoplastic elastomer, or a thermoset containing from 25 to about 400 parts of the alkaline earth metal compound per 100 parts of the polymer. A small amount of transition metal salts has further been found to greatly reduce the amount of carbon monoxide generated.
