METHOD FOR CONTINUOUSLY PRODUCING WATER-ABSORBING POLYMER PARTICLES

摘要

The invention relates to a method for continuously producing water-absorbing polymer particles by polymerizing a monomer solution containing acrylic acid and/or salts thereof, wherein the fed acrylic acid has a content of dimeric acrylic acid of at least 0.02 wt% and the content of dimeric acrylic acid is held substantially constant.
