Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
151 words
A method of producing a solid polymeric composition containing an arylmercurioxycarbonyl radical which comprises reacting in solution a polymer selected from the group consisting of homopolymers and copolymers of maleic anhydride and acrylic acid, methacrylic acid and esters thereof, said polymer containing a pendant organic radical selected from the group consisting of --COOH, --COOM, --CO--O--CO--, --COOR and mixtures thereof, wherein R is alkyl and M is a metal or ammonium cation, said polymer being essentially free of affixed alcoholic --OH groups, with an aryl mercury compound of the formula: ##STR6## wherein the substituents Y 1 to Y 5 can be the same or different and are independently selected from the group consisting of hydrogen, halogen, alkyl, alkoxy, phenyl, nitro and alkylthio and X is selected from the group consisting of halogen, hydroxy and alkylcarbonyloxy, in the presence of a solvent for the polymer, at a temperature of 140° to 180° C.
Claim 2
Independent Claim
151 words
