Abstract: AZOACYL COMPOUNDS HAVING THE FORMULA X-Y WHEREIN Y REPRESENTS A GROUP OF THE FORMULA -CO-N=N-C(-R)(-R'')-CN IN WHICH R AND R'' EACH INDIVIDUALLY IS ALKYL, WITH THE PROVISO THAT R AND R'' WHEN TAKEN TOGETHER WITH THE CARBON ATOM TO WHICH THEY ARE ATTACHED, REPRESENT A CYCLOALIPHATIC RADICAL, AND X IS SELECTED FROM THE GROUP CONSISTING OF ALKYL, ARYL, SUBSTITUTED ARYL WHICH IS SUBSTITUTED WITH 1-2 SUBSTITUENTS SELECTED FROM THE GROUP CONSISTING OF ALKYL, HALO AND A Y GROUP, ALIPHATIC, SUCH ALIPHATIE WHICH IS INTERRUPTED BY A HERTERO ATOM, AND SUCH ALIPHATIC WHICH IS SUBSTITUTED WITH A Y GROUP. THE AZOACYL COMPOUNDS ARE USEFUL AS BLOWING AGENTS FOR FORAMING PLASTIC MATERIALS SUCH A CREPE RUBBER, POLYVINYL CHLORIDE, AND THE LIKE.
