Abstract:
A composition is prepared by oxidative copolymerization of specific amounts of 2,6-dimethylphenol, 2,3,6-trimethylphenol, and a hydroxyaryl-terminated polysiloxane. The composition exhibits an increased heat resistance relative to a corresponding composition prepared by copolymerizing 2,6-dimethylphenol and hydroxyaryl-terminated polysiloxane, without 2,3,6-trimethylphenol. The composition is useful as a flame-retardant additive in polymer compositions that require high heat resistance.
