Summary for Patent: 4,366,310
|Title:|| Controlled release compositions|
|Abstract:||Molecular coordination complexes are formed between a cellulose polymer and a non-polar solid aliphatic alcohol containing 8 to 18 carbon atoms optionally substituted with an aliphatic group containing 8 to 18 carbon atoms by solvating the polymer with a volatile polar solvent and reacting the solvated cellulose polymer directly with the aliphatic alcohol, preferably as a melt. The resulting composition may be dried. This constitutes the complex. The composition has utility as a matrix in controlled release formulations since it has a uniform porosity which may be varied.|
