ABSTRACT:
Provided are enteric coating compositions which utilize a low viscosity cellulose acetate phthalate polymer as a film former. The cellulose acetate phthalates have an inherent viscosity of about 0.2 to 0.6 dL/g and phthalyl values of from 30 to 40% and can be applied to solid oral medicaments with less solvent than conventional cellulose acetate phthalate polymers. Also provided is a process for preparing the low viscosity cellulose acetate phthalate polymers.
