ABSTRACT:
Dibenzodioxaphosphepin and dibenzodioxaphosphocin derivatives are prepared by reacting selected 2,2'-biphenols with phosphorus trichloride in an organic solvent and then reacting the intermediate formed with a 1,4-dihydroxy-2,2,6,6-tetraalkylpiperidine. The phosphites formed are useful as stabilizers of organic polymers and lubricating oils, especially as process stabilizers for polyolefins, elastomers, polyesters and polycarbonates.
