A method for improving thermal stability of an organopolysiloxane characterized by compounding an organopolysiloxane (A), which was polymerized with participation of an alkali-metal catalyst, with a metal deactivater (B); and an organopolysiloxane mixture composed of an organopolysiloxane (A) characterized by compounding organopolysiloxane (A), which was polymerized with participation of an alkali-metal catalyst, with a metal deactivater (B) used in the amount of 0.02 to 1 part by mass per 10 ppm of the alkali metal contained in component (A).
