| titleOfInvention | Manufacture of homopolymer or copolymer of water-soluble vinyl monomer |
| abstract | PURPOSE: To continuously produce a (co)polymer of a water-soluble vinyl monomer with good efficiency and controllability, by forming a thin-film flow of an aqueous solution of a water-soluble vinyl monomer and a reductive sulfur- containing oxyacid salt on the inner wall of a reaction cylinder. n CONSTITUTION: An aqueous solution of a water-soluble vinyl monomer (e.g., acrylamide) 1 except α,β-unsaturated carboxylic acid monomers and a reductive sulfur-containing oxyacid salt (e.g., sodium hydrogensulfite) 3 is supplied into a reaction cylinder 10 comprising a (double)cylinder from an inlet 12. Simultaneously, an oxygen-containing gas 2 as a parallel flow to the aqueous solution is supplied into the reaction cylinder 10 from an inlet 11 to form a thin film flow of the aqueous monomer solution on the inner wall of the reaction cylinder 10 by a stream of the gas 2 to react. Then, the resulting (co)polymer of the water-soluble vinyl monomer is separated in a gas/liquid separation cooling part 4, cooled, and removed via an aging part 5 and a pH control part 6. n COPYRIGHT: (C)1988,JPO&Japio |
