摘要：
The invention provides antioxidant compounds of formula
These are made by reacting the corresponding phenol monoacrylates and disubstituted phosphonites, and are effective to stabilize organic substances, especially polyolefins against deterioration by heat, light and oxidation. A stabilized polyolefin composition preferably contains such stabilizer plus phenol-type (and optionally sulfur-containing) antioxidant.
