摘要 |
The title compounds are prepared by reacting alkylated 1,1'-biphenyl-2,2'-diol or alkylated 2,2'-alkylidene-bis-phenol with phosphorus trichloride in an organic solvent and then reacting the intermediate phosphorochlorodite with an alkanolamine. Said phosphites are useful as stabilizers of organic polymers and lubricating oils, especially as processing stabilizers for polyolefins, elastomers, polyesters and polycarbonates.
