In the production of a polymer of acrylamidoalkyl-sulphonic acid a solution of an acrylamidoalkyl-sulphonic acid monomer or salt is made. The photosensitizer is added to the solution to initiate photopolymerisation when the solution is exposed to ultraviolet light. After polymerisation the solvent content is reduced by a drying process, and the dried polymer is reduced to an appropriate particle size. The solvent may be water and the solution may also contain a monomer stabilizer or free radical inhibitor, a chain transfer agent, and a sequestering agent. |
