Polyphenolic esters of mercaptophenols as antioxidants

摘要

There is disclosed polyphenolic mercaptophenol type antioxidants, a method of preparing the antioxidants and to polymer compositions containing such polyphenolic mercaptophenol type antioxidants. In particular, polyphenolic antioxidants such as 2-(2- hydroxy-3-tertiary- butyl-5-methylbenzyl)-4-methyl-6-tertiary butyl phenyl 3-(4- hydroxyphenylthio)propionate.
