摘　　要：Propene/1-decene copolymers （P-co-D） were synthesized by means of slurry polymerization process under atmospheric pressure using Ziegler-Natta catalyst （MgCl2/TiCl4/AlEt3）. The random P-co-Ds were elastic, low-crystalline, thermally stable and therefore suitable to be used as membrane materials in organophilic pervaporation with chloroform/water mixture. Its mechanical strength is better than polydimethylsiloxane （PDMS）. The correlation between structural parameters （glass transition temperature and crystallinity） and properties of organophilic pervaporation were investigated.Propene/1-decene copolymers （P-co-D） were synthesized by means of slurry polymerization process under atmospheric pressure using Ziegler-Natta catalyst （MgCl2/TiCl4/AlEt3）.
