Abstract

Under atmospheric pressure, nano-polyethylene fibers and floccules were prepared via ethylene extrusion polymerization in situ with MCM-41-supported metallocene catalytic system. The nano-fibers and floccules were the major morphological units in the resultant samples, and the nano-fibers aggregated uniformly into aggregates and bundles. The diameter of the single fiber was 80-100 nm.With the extension of the polymerization time, the number of floccules increased. The DSC results showed that the resultant samples had higher melting point, compared with polyethylene prepared by homogeneous metallocene catalytic system in the same conditions.
