Document Type and Number:
Japanese Patent JP3349486
Kind Code:
B2
Abstract:
Production of a latex containing vinyl chloride polymer particles comprises polymerizing the corresponding monomer(s) in an aqueous microsuspension containing: (a) a water-soluble metal salt; (b) an alkali metal or ammonium salt of a fatty acid containing 8-22 carbon (C) atoms; (c) an alkali metal sulfoxylate, sulfite or metabisulfite reducing agent; (d) seed polymer particles containing an organo soluble initiator; and optionally (e) a seed polymer. Independent claims are also included for the following: (1) production of vinyl chloride polymers by drying the latex; (2) production of plastisols by mixing the polymers of with a plasticizer; (3) vinyl chloride polymers obtainable by process (1); (4) plastisols obtainable by method (2).
