Abstract
What is disclosed is a method for making a water soluble polymer of low molecular weight which forms aqueous solutions of low viscosity, which method comprises polymerizing an .alpha.,.beta.-unsaturated water soluble monomer or a mixture of such monomers in a concentrated aqueous solution of said monomer or mixture in the presence of a free radical forming initiator and of formic acid or a water soluble salt thereof as a chain transfer agent.
