Beschreibung
Zusammenfassung:	P-110 WHB: tm HYDROQUINONOID ORTHO-ALKYLATION POLYMERS AND THE PROCESS OF THEIR PRODUCTION Hydroquinonoid polymers having n reurring units of the General Structural Formula wherein n is 3 or greater, X and X' independently are hydrogen or methyl, R is a lower hydrocarbon, and R' and R'' independently are lower hydrocarbons or hydrogens are disclosed as well as such polymers additionally containing phenolic copolymerizates The preparation of these polymers by the one step copolymerization of a diolefinic hydrocarbon, a hydroquinonoid and optionally a phenolic, in the presence of an ortho-alkylation catalyst, and the use of these polymers as antioxidants, especially for foodstuffs, is also disclosed.
