Abstract (en)
[origin: WO8504885A1] Seed processes for preparing crosslinked ion exchange copolymer particles involve imbibing a seed particle with a first monomer mixture containing a minor amount of polyvinyl monomer and polymerizing the imbibed seed. A second stage monomer mixture contains a major amount of polyvinyl monomer. The second stage monomer mixture can be added either batchwise or continuously and polymerized when imbibed into the swollen seed particle. The particles so prepared exhibit good osmotic shock resistance and mechanical properties.
