ORGANOPOLYSILOXANE AND PRODUCTION METHOD THEREFOR, DISPERSANT COMPRISING ORGANOPOLYSILOXANE, AND DISPERSION CONTAINING ORGANOPOLYSILOXANE AS DISPERSANT

A dispersant is capable of giving excellent filler dispersibility in a liquid medium. The dispersant is an organopolysiloxane represented by formula (1) or (2), wherein R1 is a C1-12 saturated hydrocarbon group, X is a group represented by formula (3), acryloyl, alkyl, carboxyl, vinyl, methacryl, an...

Zusammenfassung:A dispersant is capable of giving excellent filler dispersibility in a liquid medium. The dispersant is an organopolysiloxane represented by formula (1) or (2), wherein R1 is a C1-12 saturated hydrocarbon group, X is a group represented by formula (3), acryloyl, alkyl, carboxyl, vinyl, methacryl, an aromatic group, amino, isocyanato, isocyanurato, epoxy, hydroxyl or mercapto, at least one X is a group represented by formula (3), m, l and k are 0 to 10, and j is 1 to 10. In formula (3), R2 is a C1-12 saturated hydrocarbon group or a C6-12 aromatic hydrocarbon group, Y is a C1-8 divalent hydrocarbon group, and h is 4 to 400.
