Abstract
This invention provides a process for preparing water-soluble polymers with a controlled low molecular weight, the molecular weight of the polymer being controlled by the presence of a calculated quantity of methallylsulfonate monomer during the polymerization reaction. The molecular weight of the polymer varies inversely with the quantity of methallylsulfonate monomer that is present. Low molecular weight water-soluble polymers are useful as oil well drilling additives, dispersants and the like.
