Abstract
Amines are reacted with phosphorous trichloride to form N-dichlorophosphinoamines that are then reacted with a bisphenol in about equimolar amounts to provide polyphosphoramidite oligomers. The polyphosphoramidite oligomers are effective as stabilizers for polymers such as polyolefins, and form even more efficient stabilizer combinations with hydroxyphenylalkyleneyl isocyanurates.
