Abstract
The invention provides a novel bio-based dispersant comprising the reaction product of a natural triglyceridic oil, fatty acid oil or fatty acid oil derivative wherein said natural triglyceridic oil, fatty acid oil, or fatty acid oil derivative containing greater than about 80 percent of unsaturated or conjugated unsaturated fatty acids with a substrate capable of undergoing an ene or Diels Alder reaction to form an adduct that is further esterified and/or neutralized with an alkanolamine or alkoxylated alkanolamine.
Claims18
A bio-based dispersant comprising the reaction product of a natural triglyceridic oil, fatty acid oil or fatty acid oil derivative wherein said natural triglyceridic oil, fatty acid oil, or fatty acid oil derivative containing greater than about 80 percent of unsaturated or conjugated unsaturated fatty acids with a substrate capable of undergoing an ene or Diels Alder reaction to form an adduct that is further esterified and/or neutralized with an alkanolamine or alkoxylated alkanolamine.
A bio-based dispersant selected from the group consisting of compounds of the formula:
- where R represents the additional carbon and functional moieties associated with a natural oil.
A pigment dispersion comprising:
- (a) a pigment;
- (b) a solvent;
- and (c) a bio-based dispersing agent comprising the reaction product of a natural triglyceridic oil, fatty acid oil or fatty acid oil derivative wherein said natural triglyceridic oil, fatty acid oil, or fatty acid oil derivative containing greater than about 80 percent of unsaturated or conjugated unsaturated fatty acids with a substrate capable of undergoing an ene or Diels Alder reaction to form an adduct that is further esterified and/or neutralized with an alkanolamine or alkoxylated alkanolamine.
A pigment dispersion comprising:
- (a) a pigment;
- (b) a solvent;
- and (c) a bio-based dispersant selected from the group consisting of compounds of the formula:
- where R represents the additional carbon and functional moieties associated with a natural oil.
A polymer composition comprising:
- (a) a thermoplastic resin;
- and (b) a bio-based dispersing agent comprising the reaction product of a natural triglyceridic oil, fatty acid oil or fatty acid oil derivative wherein said natural triglyceridic oil, fatty acid oil, or fatty acid oil derivative containing greater than about 80 percent of unsaturated or conjugated unsaturated fatty acids with a substrate capable of undergoing an ene or Diels Alder reaction to form an adduct that is further esterified and/or neutralized with an alkanolamine or alkoxylated alkanolamine.
