摘要：
Continuous process for producing hydrogels by charging preselected feeds containing poly(oxyalkylene) polyols, organic diisocyanate and catalyst to a reaction zone followed by crosslinking by exposure to atmospheric humidity. Solvents are not used and the hydrogels are shaped in desired configuration as they exit the extruder.
