Abstract:
1. A method for producing a minute polymer particle-containing vinyl ester resin composition, the minute polymer particle-containing vinyl ester resin composition comprising a vinyl ester resin, 1 to 100 parts by weight of minute polymer particles based on 100 parts by weight of the vinyl ester resin, and 0 to 100 parts by weight of a vinyl monomer based on 100 parts by weight of the vinyl ester resin, wherein the minute polymer particles comprise primary particles having a size of 0.05 μm to 1 μm, and the minute polymer particles are dispersed in the minute polymer particle-containing vinyl ester resin composition, and the method comprising in the following order: obtaining a loose agglomerate of minute polymer particles; obtaining a minute polymer particle dispersion; obtaining a minute polymer particle-containing polyepoxide; obtaining a minute polymer particle-containing vinyl ester resin by reacting an ethylenically unsaturated double bond-containing monocarboxylic acid with the minute polymer particle-containing polyepoxide; and adding the vinyl monomer to the vinyl ester resin.
