摘要：
Stabilizers for organic polymeric materials are provided, comprising a phosphonic acid ester, a phenolic antioxidant and a 2,2,6,6-tetramethyl-4-piperidyl ether alcohol or ether having the general formula: ##STR1## wherein R.sub.2 is lower alkyl or hydroxyalkyl having from one to six carbon atoms;R.sub.3 is a hydrogen atom, provided R.sub.2 is hydroxyalkyl; ##STR2## R.sub.2 and R.sub.3 may be taken together to form ##STR3## Y is selected from the group consisting of hydrogen and O.
