Oil soluble polymeric antioxidant prepared by condensation of divinylbenzene, hydroxyanisole, tertiary butyl hydroquinone, tertiary butyl phenol and bisphenol A under ortho alkylation conditions |
摘要 |
Phenolic polymers formed by the reaction of divinylbenzene with a mixture of hydroxyanisole, tertiary butylhydroquinone, tertiary butyl phenol and bisphenol A (and optionally para-cresol) under condensation conditions in the presence of a phenol ortho alkylation catalyst are disclosed. These materials find use as oil-soluble antioxidants especially for edibles.
