Abstract
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.
Claims15
An organopolysiloxane having a partial structure where T structural units [R1SiO3/2] are contiguously linked, wherein the partial structure where T structural units [R1SiO3/2] are contiguously linked includes a structure represented by formula (1) and a structure represented by formula (2),
- wherein in formulae (1) and (2),
- each R1 is independently a saturated hydrocarbon group having 1 to 12 carbons,
- each X is independently a group represented by formula (3), acryloyl, alkyl, carboxyl, vinyl, methacryl, an aromatic group, amino, isocyanato, isocyanurato, epoxy, hydroxyl, or mercapto, wherein at least one X is a group represented by formula (3),
- m, l, and k are each independently 0 to 10, and
- j is 1 to 10;
- wherein in formula (3),
- each R2 is independently a saturated hydrocarbon group having 1 to 12 carbons, or an aromatic hydrocarbon group having 6 to 12 carbons,
- Y is a divalent hydrocarbon group having 1 to 8 carbons, and
- h is 4 to 400.
