          Appeal No. 95-0365                                                          
          Application 07/921,537                                                      

               The appellants contend that those skilled in the art would             
          understand the referenced statement to mean that “if the reaction           
          rate is important to the selected end use, a composition without            
          metal drier should be cured at elevated temperature.”  Brief,               
          p. 4, para. 2.  We disagree.  We find nothing in the referenced             
          sentence which suggests performing the autoxidation reaction at a           
          different temperature, either higher or lower.  Although the                
          appellants urge that those skilled in the art would have                    
          understood the phrase as suggesting an elevated temperature, they           
          have not provided any evidence which supports that position.                
               Accordingly, Rejection I is affirmed.                                  

                                    Rejection II                                      
               According to the examiner, Bors discloses “polymers having             
          acetoacetate functionality introduced on the chain end by an                
          acetoacetate functional mercaptan.”  Answer, p. 3.  In addition,            
          the examiner states that Gresham describes a method for                     
          endcapping formaldehyde polymers with alcohols and that Huyser              
          discloses that the appellants’ end groups are autoxidizable.                
          Answer, p. 4.  Accordingly, the examiner concludes that                     
               it would have been obvious to one of ordinary skill in the             
               art that if autoxidizable alcohol endgroups where [sic,                
               were] used in the known method of making end-blocked
