          component for polymerizing ethylene formed by a particular                  
          process.  Claim 1 is representative and reads as follows:                   


          1.   A catalyst component for ethylene polymerization formed                
          by:                                                                         
               (1) initially reacting a metal oxide support with an                   
                         organomagnesium compound to form a supported                 
                         organomagnesium composition;                                 
               (2) reacting the supported organomagnesium composition                 
          with           an alkoxy silane;                                            
               (3) contacting the product from step (2) with a                        
                         chlorinating reagent; and                                    
               (4) contacting the product from step (3) with a liquid                 
                    titanium halide.                                                  
               The references relied upon by the examiner are:
