         Appeal No. 1999-2507                                                        
         Application No. 08/967,367                                                  



         50 mol% of an á-olefin having 3 or more carbon atoms, and 2 to              
         20 mol% of a cycloolefin such as tetracyclo[4.4.0.1 2,5.17,10]-3-           
         dodecene.  (Column 12, line 37 to column 26, line 2.)  Yamamoto             
         further teaches that the thermoplastic resin composition may                
         additionally contain other resins such as an                                
         acrylonitrile/butadiene/styrene copolymer, acrylonitrile/styrene            
         copolymer, or acrylonitrile/styrene/acrylic acid ester copolymer.           
         (Column 29, lines 32-50.)                                                   
              The examiner determined that neither Brekner nor Yamamoto              
         describes the particulate core/shell component recited in                   
         appealed claims 9 and 14.  To account for this difference, the              
         examiner relied on Laughner.                                                
              Laughner teaches a composition for blow molding processes              
         comprising about 75 to about 99.999% by weight of a                         
         thermoplastic polymeric material, about 0.001 to about 5% by                
         weight of a fluorinated olefin polymer, and optionally up to                
         about 20% by weight of an elastomeric impact modifier.  (Column             
         2, lines 7-30; 48-66.)  The examiner determined (examiner's                 
         answer, page 5), and the appellants appear to concede (appeal               
         brief, page 7), that Laughner describes a specific elastomeric              
         impact modifier (i.e., an MBS core/shell elastomer) falling                 
         within the scope of the appealed claims as the recited                      
         particulate core/shell component.  (Column 10, line 66 to column            


                                         4
