Studies on polymer stabilizers: Part IV—Prevention of oxidative discoloration

By a model accelerated oxidative reaction and product analysis, 2- tert-butyl-6-(3- tert-butyl-2-hydroxy-5-methylbenzyl)-4-methylphenyl acrylate (Sumilizer® GM) was found to give a stilbene quinone-type colored product through a quinone methide-type intermediate. The resistance of GM and its analogs...

Description
Summary:By a model accelerated oxidative reaction and product analysis, 2- tert-butyl-6-(3- tert-butyl-2-hydroxy-5-methylbenzyl)-4-methylphenyl acrylate (Sumilizer® GM) was found to give a stilbene quinone-type colored product through a quinone methide-type intermediate. The resistance of GM and its analogs against oxidative discoloration was remarkably improved by substitution with a bulky group at the para position to the phenolic OH group.
