Methyl Ethyl Ketone → Styrene acrylic acid copolymer

Participants

Reaction Steps

A true spherical silica fine particle (“SEAHOSTER KEP150”, produced by Nippon Shokubai K.K.) having an average particle size of 1.5 μm (10 parts), 2 parts of a dispersant polymer (“JONCRYL 611”, acrylic acid ester styrene copolymer, produced by Johnson Polymer), 16 parts of methyl ethyl ketone and 64 parts of N-methylpyrrolidone were mixed, and the resulting mixture was put in a 200 ml-volume polyethylene-made container together with 30 parts of glass bead having a diameter of 2 mm and dispersed for 2 hours by a paint shaker (manufactured by Toyo Seiki) to obtain a silica fine particle dispersion.
