摘要:
Substituted 2-(2,6-di-t-butyl-4-alkylphenoxy)-4H-1,3,2-benzodioxaphosphorins that are readily prepared, for example from hindered phenols and ortho-methylolphenols, are effective heat and anti-oxidant stabilizers for organic materials subject to degradation by heat and oxygen, and provide particularly efficient stabilizer systems when combined with hydroxyphenylalkyleneyl isocyanurates.
