Abstract

PURPOSE: To prepare a highly stable aqueous dispersion of a vinyl polymer giving coating film having excellent water resistance, by polymerizing a vinyl monomer in an aqueous medium in the presence of a specific water-soluble acrylic polymer having tertiary sulfonium salt groups.
CONSTITUTION: In the presence of (A) 100 parts by weight of a water-soluble acrylic polymer having one or more tertiary sulfonium salt groups I (R1 and R2 are organic group; Yθ is anion) in a molecule on an average, and a number average molecular weight of 4,000W40,000, preferably containing 5W20 (meth) acrylic ester units having tertiary sulfonium salt groups II (R3 is H or methyl; R4 is alkyl, hydroxyalkylene, etc.), and (B) 0.5W8 parts by weight of a catalyst, (C)≤ 2,000, preferably 100W1,000 parts by weight of a vinyl monomer III R5 is H or methyl; Q is COOR6, IV, etc.; R6 is H or organic group; R7 and R8 are H, lower alkyl, etc.) is polymerized in an aqueous medium (e.g. methanol, etc.) preferably at 70W100°C for 8W10 hours.
