ABSTRACT:
Process for the synthesis of hindered polysubstituted .alpha.-amino acetamides which comprises first reacting an .alpha.-haloacetamide with a base to form an intermediate .alpha.-lactam which in turn is reacted with a primary or secondary amine. The product thus obtained can comprise a multifunctional compound having one or more hindered amino moieties. These compounds are highly effective as UV stabilizers in a variety of plastics, especially the alpha monoolefins.
