PROBLEM TO BE SOLVED: To provide a thermal stabilizer composition for a halogen-containing vinyl polymer. SOLUTION: A synergistic stabilizer composition is employed to stabilize a halogen-containing vinyl polymer from, for example, degradation and discoloration. The stabilizer composition comprises an aromatic amine and at least one kind of additional co-stabilizer. The co-stabilizer is a dihydropyridine, a polydihydropyridine, an aminoalcohol, a perchlorate, a polyol, a sterically hindered amine, a hydrotalcite, a mercaptan-containing organic compound, or a mixture comprising one or more of the foregoing co-stabilizers. A halogen-containing vinyl polymer composition comprising an aromatic amine and an article comprising the polymer composition are also provided. COPYRIGHT: (C)2006,JPO&NCIPI
