| 摘要 |
The present invention relates to a process for the production of concentrated, water-soluble or water swellable emulsion polymers by the polymerisation of at least one water-soluble monomer in a water-in-oil dispersion by means of polymerisation initiators, optionally in presence of bi- or multi-function vinyl- or allyl compounds in which a water-in-oil dispersion of the starting monomers is polymerized whilst being stirred so that the heat of polymerisation is eliminated by distillation removal of the water contained in the reaction mixture. The polymerisation temperature is preferably adjusted and controlled by means of the pressure in the system. |
