Beneficial stabilizer compositions are employed to stabilize halogen-containing vinyl polymers from, for example, degradation and discoloration. The stabilizer compositions comprise a substantially metal-free perchlorate; a first amine-containing stabilizer; and a second amine-containing stabilizer; wherein the first and second amine-containing stabilizers are selected from an aminoalcohol, a dihydropyridine, an aminocrotonate, an aminouracil, a phenyl indole, or a mixture comprising one or more of the foregoing amine-containing stabilizers; and wherein the first and second amine-containing stabilizers are different types of stabilizers.
