中文摘要	macroporous and modified macroporous poly(styrene-co-methyl methacrylate-co-divinylbenzene) particles (m-ps and mm-ps) supported cp2zrcl2 were prepared and applied to ethylene polymerization using methylaluminoxane (mao) as cocatalyst. the influences of the swelling response of the support particles on the catalyst loading capabilities of the supports as well as on the activities of the supported catalysts were studied. it was shown that the zr loadings of the supports and the activities of the supported catalysts increased with the swelling extent of the support particles. the m-ps or mm-ps supported catalysts exhibited very high activities when the support particles were well swollen, whereas those catalysts devoid of swelling treatment gave much lower activities. investigation on the distribution of the supports in the polyethylene by tem indicated that the swelling of the support particles allowed the fragmentation of the catalyst particles. in contrast, the fragmentation of the support particles with poor swelling was hindered during ethylene polymerization.
