| 摘要 |
Aqueous solutions of copolymers and/or terpolymers obtained from monomers of acrylic and/or methacrylic acids, their sodium, potassium or ammonium salts, aliphatic derivatives of said acids with linear alcohols of one to three carbon atoms and derivatives of said acids with phenyl, p-hydroxyphenyl, phenyl-4-sulphonic groups and other products derived from the phenyl and/or naphthyl groups. They are characterized in that one of said monomers corresponds to the general formula I, where R1 corresponds to a hydrogen, methyl or hydroxyl and R2 corresponds to phenyl, p-hydroxyphenyl etc. and in that said monomer, referred to as a tracer, has fluorescence properties and when chemically combined, to form the copolymer and/or terpolymer, transfers said fluorescence properties. This allows the continuous control and analysis of said polymers in the treatment of industrial water. <CHEM> <IMAGE> |
