    摘要: Polysubstituted .alpha.-aminoacetamides of the formula ##STR1## wherein R.sup.1 is tert-alkyl; R.sup.4 is alkyl, phenyl, substituted phenyl, cycloalkyl, piperidinyl, tetraalkylpiperidinyl or an alkylene (.alpha.-aminoacetamide). These compounds are prepared by first reacting an .alpha.-haloacetamide with a base to form an .alpha.-lactam intermediate which in turn is reacted with a primary amine. The compounds are useful as stabilizers of polymeric materials against ultraviolet light degradation.
