Polymer blends having reverse phase morphology for controlled delivery of bioactive agents |
| abstract |
POLYMER BLENDS HAVING REVERSE PHASE MORPHOLOGY FOR CONTROLLED DELIVERY OF BIOACTIVE AGENTS Abstract Disclosed are polymer blends containing a minor amount of cellulose acetate and a major amount of cellulose acetate phthalate, cellulose acetate trimellitate or cellulose acetate succinate. The blends have reverse phase morphology, that is, the minor component forms a continuous phase. The blends are useful for zero-order controlled delivery of bioactive agent such as pharmaceutical and agricultural chemicals. |
