Polyethers containing 2,2,6,6-tetramethyl piperidinyl carboxylic acid ester groups and synthetic resin compositions

摘要

Polyethers containing 2,2,6,6-tetramethyl piperidinyl carboxylic acid ester or ether groups are provided, comprising polymeric units having the structure <IMAGE> I wherein X is selected from the group consisting of: <IMAGE> <IMAGE> <IMAGE> <IMAGE> <IMAGE> R1 is selected from the group consisting of hydrogen, -O, alkyl, hydroxy alkyl and epoxyalkyl having from one to about eighteen carbon atoms, acyl having from one to about eighteen carbon atoms, cycloalkyl having from three to about eighteen carbon atoms; phenyl; phenalkyl and alkylphenyl having from seven to about twenty-four carbon atoms; R2 is hydrogen or hydroxy; n1 is 0 or 1; R3 is lower alkyl having from one to about six carbon atoms; and n is the average number of such units in the polymer; as well as stabilized synthetic resin compositions comprising such polyethers.
