Abstract
2-[Alkyl substituted-phenoxy]-2,3-dihydro-1,2-benzoxaphosphole 2-oxide, cyclic phosphonates prepared, for example from hindered phenols and ortho-methylolphenols, are effective heat stabilizers and antioxidants for organic materials subject to degradation by heat, oxygen and the like, and result in effective stabilizer systems when combined with hydroxyphenylalkylenyl isocyanurates.
