| titleOfInvention | Heterobifunctional polyethylene glycol derivatives and methods for their preparation |
| abstract | A method for preparing heterobifunctional derivatives of poly (ethylene glycol) or related polymers in high purity and yield. An intermediate polymer having the formula W-poly-OH having a removable W group at one end can be provided without going through a chromatographic purification step. , First converting the OH group to the first functional group X, then removing W to produce a second hydroxyl group, and then converting the latter hydroxyl group to the second functional group Y Can be converted to give the desired heterobifunctional derivative. [Selection figure] None |
