abstract |
Compounds of formula I ##STR1## wherein R 1 , R 2 , R 3 and R 4 are each 2-ethylhexyl or are independently higher alkyl, or R 1 and R 2 are independently hydrogen or methyl, and R 3 and R 4 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. |
