Abstract

Arylsulfonamides (ASA), methanesulfonamide (SA-9) and arylamides (AAA) of p-aminodiphenylamine have been prepared as heat stabilizer, and their antioxidation activities for low density polyethylene (LDPE) have been evaluated by TG/DTA curve.<br>Every ASA, in paticular hologen or methoxy substituted phenyl derivatives and naphthyl derivatives, have showed the high antioxidation activity for LDPE. On the other hand, antioxidation activities of SA-9 and AAA have proved to be poor, indicating that arylsulfonylamide group of ASA is essential for their high antioxidation activities.<br>The brief mechanism including the formation of benzoquinone diimine has been put forward in favor of such superior performance of ASA in Fig. 6
