PROBLEM TO BE SOLVED: To improve the storage stability of a polymer itself or a curable composition containing the polymer, or to prevent corrosion of a reactor or various materials in contact with the polymer. . In particular, it greatly improves the storage stability of a polymer having a crosslinkable silyl group. SOLUTION: A vinyl polymer having a halogen group is treated with an oxyanion compound to reduce the halogen content in the polymer. |
