    摘要: Disclosed is an adhesive composition. The adhesive composition comprises a maleated polyolefin and an LLDPE. The LLDPE is made by a Ziegler-Natta catalyst which comprises a MgCl2 support, a Ti(IV) complex, and an electron donor. The catalyst has an Mg/Ti molar ratio greater than or equal to 7. Preferably, the Ti(IV) complex is TiCl4, and the electron donor is tetrahydrofuran. Preferably, the adhesive comprises from 35 to 95 wt % of the LLDPE and 5 to 65 wt % of maleated polyolefin.

    摘要: Terpolymers of ethylene, vinyl acetate and isobutylene as flow improvers in distillate fuels. The terpolymers have number average molecular weights in the range of about 1,600 to about 3,000, and weight average molecular weights in the range of about 4,000 to about 18,000. These terpolymers provide improved low temperature flow characteristics in middle distillate fuels.
