          Application 08/223,351                                                       






                                 DECISION ON APPEAL                                    
                    This is an appeal pursuant to 35 U.S.C. § 134 from the             
          final rejection of claims 1 and 4 through 24.                                
                    The subject matter on appeal is related to a process for           
          producing a low molecular weight copolymer product containing rela-          
          tively low levels of a monoethylenically unsaturated dicarboxylic            
          acid monomer component.  Representative appealed claim 1 is repro-           
          duced below:                                                                 
                    1.  A polymerization process, comprising:                          
                    a) establishing an initial charge of water in a                    
          reactor;                                                                     
                    b) adding into the reactor to form a reaction mixture              
                         i)   at least one water soluble chain transfer                
                         agent selected from alkali metal salts of                     
                         sulfites;                                                     
                         ii)  at least one water soluble initiator,                    
                         iii) at least one metal promoter,                             
                         iv)  from about 50 to about 97 weight percent,                
                         based on the total weight of monomer added to                 
                         the reactor, of at lest one water soluble mono-               
                         ethylenically unsaturated monocarboxylic acid                 
                         monomer,                                                      
                                           2
