Abstract
In a process for producing water-absorbing polymeric particles which comprises generating droplets comprising monomers, polymerizing the monomers in a heated gas phase surrounding the droplets and flowing the gas through the polymerization reactor, the temperature of the gas leaving the polymerization reactor is closed-loop controlled.
Claims10
A process for producing water-absorbing polymeric particles which comprises generating droplets comprising monomers, polymerizing the monomers in a heated gas phase surrounding the droplets and flowing a gas through a polymerization reactor, wherein a temperature of the gas leaving the polymerization reactor is closed-loop controlled to provide a constant gas outlet temperature.
