Dispersant compositions containing glycerol carbonate and polyester-based dispersants
View Patent ↗Dispersant compositions are described which contain: (a) a carrier medium comprising glycerol carbonate, the carrier medium present in an amount of from 10 to 80% by weight based on the composition; and (b) one or more polyester dispersants present in an amount of from 20 to 90% by weight based on the composition.
1. A dispersant composition consisting of:
(a) a carrier medium consisting of glycerol carbonate, the carrier medium present in an amount of from 10 to 80% by weight based on the composition; and
(b) one or more polyester dispersants present in an amount of from 20 to 90% by weight based on the composition.
2. A dispersant composition comprising:
(a) a carrier medium comprising glycerol carbonate, the carrier medium present in an amount of from 10 to 80% by weight based on the composition; and
(b) one or more polyester dispersants present in an amount of from 20 to 90% by weight based on the composition, wherein the one or more polyester dispersants comprises a carboxyl-containing polyester, wherein at least 5% by weight of the carboxyl-containing polyester is water-soluble in the neutralized state, and wherein at least 20% by weight of the carboxyl-containing polyester is soluble in glycerol carbonate in the acidic state.
3. A dispersant composition comprising:
(a) a carrier medium comprising glycerol carbonate, the carrier medium present in an amount of from 10 to 80% by weight based on the composition; and
(b) one or more polyester dispersants present in an amount of from 20 to 90% by weight based on the composition, wherein the one or more polyester dispersants comprises a polyester having ethylene oxide oligomer structural elements.
4. The dispersant composition according to claim 2 , wherein the carboxyl-containing polyester further comprises ethylene oxide oligomer structural elements.
5. The dispersant composition according to claim 1 , wherein the composition is substantially free from volatile organic compounds.
6. The dispersant composition according to claim 2 , wherein the composition is substantially free from volatile organic compounds.
7. The dispersant composition according to claim 3 , wherein the composition is substantially free from volatile organic compounds.
8. The dispersant composition according to claim 4 , wherein the composition is substantially free from volatile organic compounds.
9. The dispersant composition according to claim 1 , wherein the composition is liquid and pourable at 25° C.
10. The dispersant composition according to claim 2 , wherein the composition is liquid and pourable at 25° C.
11. The dispersant composition according to claim 3 , wherein the composition is liquid and pourable at 25° C.
12. The dispersant composition according to claim 4 , wherein the composition is liquid and pourable at 25° C.
13. The dispersant composition according to claim 5 , wherein the composition is liquid and pourable at 25° C.

wherein the composition is liquid and pourable at 25° C. and wherein the composition is substantially free from volatile organic compounds.
16. The dispersant composition according to claim 15 , wherein the one or more polyester dispersants comprises a polyester having ethylene oxide oligomer structural elements.
17. The dispersant composition according to claim 15 , wherein the carboxyl-containing polyester further comprises ethylene oxide oligomer structural elements.
18. A paint formulation comprising a dispersant composition comprising:
