Erythorbate as part of a redox initiator system for the polymerization of water-swellable polymers.

摘要

This invention relates to a process for polymerizing an aqueous solution of an alpha , beta -ethylenically unsaturated monomer and at least one crosslinking monomer to produce a water-swellable polymer using erythorbate as a component of a redox initiator system. The use of erythorbate as a component of a redox initiator system for the polymerization allows for controlling the temperature of initiation so as to decrease heat release during polymerization without sacrificing excellent polymer properties.
