Sterically hindered derivatives of water soluble polymers |
| abstract |
The invention provides a sterically hindered polymer that comprises a water-soluble and non-peptidic polymer back-bone having at least one terminus covalently bonded to an alkanoic acid or alkanoic acid derivative, wherein the carbon adjacent to the carbonyl group of the acid or acid derivative group has an alkyl or aryl group pendent thereto. The steric effects of the alkyl or aryl group allow greater control of the hydrolytic stability of polymer derivatives. The polymer backbone may be poly(ethylene glycol). |
