Title:
LOW-MOLECULAR WEIGHT CELLULOSE-MIXED ESTERS AND THEIR USE AS LOW VISCOSITY BINDERS AND MODIFIERS IN COATING COMPOSITIONS
Document Type and Number:
Japanese Patent JP2012021163
Kind Code:
A
Abstract:

To provide low-molecular weight cellulose-mixed esters that has low degree of polymerization and are useful in coating and ink compositions as low viscosity binder resins and rheology modifiers.

This invention relates to cellulose-mixed esters having a total degree of substitution per anhydroglucose unit of from about 3.08 to about 3.50, and having the following substitutions: a degree of substitution per anhydroglucose unit of hydroxyl of no more than about 0.70; a degree of substitution per anhydroglucose unit of C3-C4 esters from about 0.80 to about 1.40, and a degree of substitution per anhydroglucose unit of acetyl of from about 1.20 to about 2.34. The mixed esters exhibit an inherent viscosity from about 0.05 to about 0.12 dL/g, as measured in a 60/40 (wt./wt.) solution of phenol/tetrachloroethane at 25[deg.] °C; a number average molecular weight (Mn) of from about 1,000 to about 5,600; a weight average molecular weight (Mw) of from about 1,500 to about 10,000; and a polydispersity of from about 1.2 to about 3.5.
