| titleOfInvention | Production of w/o emulsion |
| abstract | PURPOSE: To produce a W/O emulsion while suppressing the formation of agglomerates during polymerization by decreasing the concentration of dissolved oxygen in the emulsion during polymerization below a specified value in the production of a W/O polymer emulsion from a water-soluble vinyl monomer. n CONSTITUTION: A process for producing a W/O emulsion of a water-soluble polymer by polymerizing a water-soluble vinyl monomer in a W/O emulsion, wherein the concentration of dissolved oxygen in the emulsion during polymerization is adjusted to 100ppb or less. Examples of the water-soluble vinyl monomers include acrylamide, acrylic acid (salt) and dimethylaminoethyl (meth)acrylate. An aliphatic hydrocarbon is desirable as the hydrophobic liquid used for the formation of the W/O emulsion. As the emulsifying surfactants desirable for forming emulsions, those having an HLB of 2-6 are desirable, and their examples include sorbitan monooleate and polyoxyethylene nonylphenyl ether. n COPYRIGHT: (C)1991,JPO&Japio |
