  • Haze-free boronated antioxidant
    Patent number: 4927553
    Abstract: An additive composition of boronated phenolic antioxidant and anti-haze diol capable of complexing with boric acid as well as organic material protected by the additive composition. A hydrolytically stable additive composition comprising a boronated phenolic antioxidant and a diol member capable of reacting with boric acid formed as a hydrolysis product to form a stable ring structure soluble in a substrate. The additive composition prevents or cures a haze caused by hydrolysis.
