Abstract
Official abstract text for this publication.
The present invention relates to a composition comprising triethylene glycol disorbate and triethylene glycol monosorbate, at a disorbate to monosorbate weight-to-weight ratio of from 19:1 to 99:1. The composition of the present invention is useful as a low VOC coalescent in coatings formulations.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition comprising triethylene glycol disorbate and triethylene glycol monosorbate, wherein the weight:weight ratio of the disorbate to the monosorbate is from 19:1 to 99:1. 2. The composition of claim 1 wherein the weight:weight ratio of the disorbate to the monosorbate is from 19:1 to 65.6:1. 3. The composition of claim 1 wherein the weight:weight ratio of the disorbate to the monosorbate is from 24:1 to 99:1. 4. The composition of claim 1 wherein the weight:weight ratio of the disorbate to the monosorbate is from 24:1 to 65.6:1. 5. The composition of claim 1 wherein the weight:weight ratio of the disorbate to the monosorbate is from 32:1 to 99:1. 6. The composition of claim 1 wherein the weight:weight ratio of the disorbate to the monosorbate is from 32:1 to 65.7:1. 7. The composition of claim 1 wherein the weight:weight ratio of the disorbate to the monosorbate is from 39:1 to 99:1. 8. The composition of claim 1 wherein the weight:weight ratio of the disorbate to the monosorbate is from 39:1 to 65.7:1. 9. The composition of claim 4 which composition further comprises less than 1 weight percent gelled byproducts having a molecular weight of greater than 5000 Daltons, as determined by self-diffusion coefficient measurements using Pulse Field Gradient NMR spectroscopy. 10. The composition of claim 6 which composition further comprises less than 0.1 weight percent gelled byproducts having a molecular weight of greater than 5000 Daltons, as determined by self-diffusion coefficient measurements using Pulse Field Gradient NMR spectroscopy.
