    摘要: A thermal stabilizer for organopolysiloxane oils is disclosed. The stabilizer is formed by the reaction of (A) an organopolysiloxane with (B) an aromatic aminophenol in the presence of (C) a quaternary phosphonium hydroxide, or in the presence of both the quaternary phosphonium hydroxide comprising component (C) and (D) an organopolysiloxane cyclic. Organopolysiloxane oils containing said thermal stabilizer are not subject to viscosity increases or gelation in long-term heating at high temperatures. Furthermore, such combinations show very little viscosity decline in long-term heating at high temperatures.
