Abstract
Aqueous monomer solutions comprising free-radically polymerizable monomers and at least 55% by weight of water are spray polymerized to prepare crosslinked, water-swellable polymers.
Claims20
The A process for spray polymerization in an inert atmosphere of a monomer solution comprising free-radically polymerizable monomers wherein a water content of the monomer solution is in the range from 60% to 95% by weight and a reaction temperature is in a range from 90 to 300° C.
