Linear low density polyethylene (LLDPE)/[C14 mim]Br blends were prepared via melting blend, with the structure and properties of the blends determined and tested. Results of testing indicate that [C14 mim]Br can have a heterogeneous nucleating effect in the matrix, which makes the crystal of LLDPE grow bigger with increasing amount of [C14 mim]Br. The onset crystallization temperature of the blends is higher than that of neat LLDPE at the same cooling rates. In addition, the presence of [C14 mim]Br can improve the antistatic properties of LLDPE apparently. The lowest surface resistance is 1.8·108 Ω with about 2.0 phr content of [C14 mim]Br in the blends. Moreover, the melt index of LLDPE increases with the amount of [C14 mim]Br increasing. As for mechanical properties, the tensile strength increases at first then decreases slowly, while the impact strength presents the opposite results when the dosage of [C14 mim]Br increases in the LLDPE, so [C14 mim]Br plays an anti-plasticized and plasticized role to PP.
