ABSTRACT OF THE DISCLOSURE A process for the preparation and purification of mixed aromatic-aliphatic phosphites which enables an improved process using such purified aromatic aliphatic phospites for the preparation of stabilized polymers. The process involves the reaction of an alkylphenol with diphenyl-(or a lower dialkyl-) pentaerythritol diphosphite. The process is simple and inexpensive, and produces a relatively pure product.
