Methods for producing the polymers and their use for mineral processing such as kaolin and calcium carbonate beneficiation are described. The method for producing the polymer includes a step of polymerizing at least one monomer in the presence of a polymerization initiator, a chain transfer agent, and a polymerization stabilizer to produce a polymer having at least one carboxylic acid. And the at least one monomer comprises an unsaturated carboxylic acid monomer, and the polymer having the at least one carboxylic acid is stable and has a molecular weight of from about 1000 g / mol to about 10,000 g / mol.
