Improved process for synthesis of hindered amine stabilizers for polymeric materials.

摘要

Process for the synthesis of hindered polysubstituted alpha -amino acetamides by reaction of a secondary amine with an alpha -halo acetamide in a basic organic reaction medium and in the presence of a phase transfer catalyst. 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.
