Model Silica Supported Olefin Polymerization Catalystseatments, TiC1. can be reacted with various surface bonding geometries. Most surface characterization was done acing diffuse reflectance FTIR spectroscopy. The TiC1. reacted silica gels, after reaction with Al(Et)., give catalysts which polymerize ethylene and 1-butene with different activities and

Supported Lewis Acid Catalysts Based on Polyolefin Thermoplasticser purification. All of them also save energy and environment. These considerations become even more important when the reactions require a large quantity of catalyst, such as in the oligomerization of olefins. Figure I illustrates the reaction process. The catalyst involves in the oligomerization r

Homogeneous Reaction of Maleic Anhydride with Low Density Polyethylene in Solution in Aromatic Hydronditions. The heterogeneous reactions have been carried out with molten LDPE , in which MAH is insoluble and with LDPE film suspended in acetic anhydride , while the homogeneous reactions have been carried out with LDPE and HDPE in xylene solution , using peroxidic catalysts at high con
