Abstract:
A polymerizable dispersant for use in nonaqueous, filled suspensions comprising:a polycaprolactone-modified monophosphate ester of the formula â€ƒwherein R is a (meth)acrylate group radical or vinyl radical and n represents the number of units of caprolactone, and wherein the monophosphate ester is selected from the group consisting of: (a) polycaprolactone-modified polypropylene glycolmethacrylate phosphate prepared from a mole ratio of caprolactone:polypropylene glycolmethacrylate of 2:1, (b) polycaprolactone-modified glycerol dimethacrylate phosphate prepared from a mole ratio of caprolactone:glycerol dimethacrylate of 2:1, (c) polycaprolactone-modified glycerol dimethacrylate phosphate prepared from a mole ratio of caprolactone:glycerol dimethacrylate of 5:1, (d) polycaprolactone-modified dipentaerythritol pentaacrylate phosphate prepared from a mole ratio of caprolactone:dipentaerythritol pentaacrylate of 2:1, (e) polycaprolactone-modified dipentaerythritol pentaacrylate phosphate prepared from a mole ratio of caprolactone:dipentaerythritol pentaacrylate of 5:1, (f) polycaprolactone-modified polyethyleneglycol methacrylate phosphate prepared from a mole ratio of caprolactone:polyethyleneglycol methacrylate of 2:1, and (g) polycaprolactone-modified polyethyleneglycol methacrylate phosphate prepared from a mole ratio of caprolactone:polyethyleneglycol methacrylate of 5:1.
