Process for producing water-insoluble polymers of uniform shape from gelled salts of alginic acid |
| abstract |
A process for producing a water-insoluble polymer of uniform shape having high strength and a desired geometric form is disclosed. This process comprises the steps of dissolving or partially suspending in water (a) a water-soluble salt of alginic acid, (b) a hydrophilic, crosslinkable vinyl monomer having two or more radical-polymerizable vinyl groups per molecule, and (c) optionally a hydrophilic, radical-polymerizable vinyl monomer; bringing the resulting aqueous solution or suspension into contact with an aqueous solution capable of causing gelation of the water-soluble salt of alginic acid and thereby forming an water-insoluble gel of uniform shape; and subjecting the gel to radical polymerization to produce a water-insoluble polymer. |
