ABSTRACT
Aromatic nonhindered phosphite 43 is an effective storage stabilizer in unsaturated elastomers (9). Aliphatic 39 and mixed aliphatic-aromatic phosphites 41, 42 are costabilizers and metal-complexing additives in PVC (32). Cyclic dioxaphosphocin 45, containing an amine moiety, and fluorophosphonite 47 resulted from development of phosphorus stabilizers having a higher inherent resistance to hydrolysis.
