Abstract: A starchbased antistatic agent was first prepared, and then the antistatic polypropylene (PP) compounds were prepared by meltblending of PP with the antistatic agent. The effects of the antistatic agent on the surface resistivity of PVC compounds were investigated when being used individually or combined with nonionic antistatic agent, ionic antistatic agent and inorganic salt. The results indicated that the combination of the starchbased antistatic agent with the ionic antistatic agent could lead to a synergistic effect on PP and thus resulted in excellent antistatic performance and durability.

Key words: polypropylene, starchbased antistatic agent, durability, synergistic effect
