Thermal oxidation stabilizer composed of phosphite derivatives of an alcohol and PPE monomer still bottoms, and PPE compositions containing said phosphites

摘要

Novel compositions comprising a mixture of two or more phosphites derived from monomer still bottoms from the orthoalkylation of phenols are made by reacting a phosphorous halide with the still bottom. The monomer still bottom phosphites are effective as thermal oxidative stabilizers for engineering themoplastics, such as polyphenylene ether resins.
