Abstract
Liquid organic phosphites of low volatility, based on pentaerythritol, alkyl alcohols and alkyl phenols, which are essentially phenol-free are disclosed. These phosphites are excellent stabilizers for polymers, especially PVC resins. The phenol-free phosphite stabilizers are compatible with mixed metal stabilizers and give excellent color and processing stability.
