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, 2Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 NextLast modified: November 3, 2007
