| abstract |
The present invention provides a method for forming compounds of Formula n HO—C(═O)R 1 —X—R 2 —X—R 1 —C(═O)—O—H n wherein compound (I) can be polymerized to provide a polymer that contains therapeutically active compounds. In the compounds of the invention, each R 1 is group that will provide the therapeutically active compound upon hydrolysis of the polymer; each X is independently an ester linkage or an amide linkage; and R 2 is a linking group. |
