abstract |
Compounds of formula In n wherein R₁, R₂, R₃ and R₄ are each 2-ethylhexyl or are independently higher alkyl, or R₁ and R₂ are independently hydrogen or methyl, and R₃ and R₄ are independently higher alkyl are effective processing stabilizers for polymers processed at elevated temperatures by preventing polymer degradation and providing resistance to discoloration. The compounds of formula I also exhibit superior hydrolytic stability and resist moisture pickup on storage. |
