Polypropylene (PP)/1

4-bis(3-tetradecylimidiazolium-1-yl)butane bromide (Br［C14im］(CH2)4［C14im］Br) blends were prepared via melting blending

and then the structure and properties of the blend were characterised and tested.Results of testing indicate that Br［C14im］(CH2)4［C14im］Br could have a heterogeneous nucleating effect in the PP matrix.Moreover

PP was readily to form α crystal in the PP crystallizing process with the help of Br［C14im］(CH2)4［C14im］Br.XRD data show the crystallizing process of PP could be affected by Br［C14im］(CH2)4［C14im］Br

and thus decreased the crystallinity of PP.DSC results show the melting point and the crystallization temperature of PP/Br［C14im］(CH2)4［C14im］Br blends was close to that of neat PP

this maybe due to the good compatibility of PP to Br［C14im］(CH2)4［C14im］Br with long alkyl chains.In addition

the presence of Br［C14im］(CH2)4［C14im］Br could improve the antistatic properties of PP apparently

and the surface resistivity of the PP was decreased to 8.97×109 Ω cm when the content of Br［C14im］(CH2)4［C14im］Br in the blends was about 3 phr.As for the mechanical properties

the tensile strength decreased while the impact strength of materials presented the opposite results with Br［C14im］(CH2)4［C14im］Br incorporated into it.DMA results show the glass transition (Tg) of PP also decreases when 3 phr Br［C14im］(CH2)4［C14im］Br exists in its matrix.Therefore

Br［C14im］(CH2)4［C14im］Br has the plasticized effect on the PP matrix in our experiments.
