Abstract: Aromatic, aliphatic and mixed-type diacylhydrazines were synthesized. Their crystal nucleating activity for polypropylene was measured by DS C. Their copper-deactivating activity for polypropylene was evaluated by the aging test at 150 IC. Their melting point, entropy of fusion, and wave number of IR absorption band for N-H bond, were also measured. These properties of diacylhydrazines were analyzed by correlational and multiple regression analysis. Thus, it was found that diacylhydrazines with high crystal nucleating activity show high copper-deactivating activity. The aging life of poly-propylene stabilized by a new diaeylhydrazine can be calculated by the multiple regression equation where the prediction variables are the crystal nucleating activity and above mentioned properties of diacylhydrazine.
