| Popis: | We describe the preparation of telechelic OH-terminated poly[(R)-3-hydroxybutyric acid] (PHB) and poly{[(R)-3-hydroxybutyric acid]-co-[(R)-3-hydroxyvaleric acid]} (PHB/HV), on a semi-preparative scale, by a transesterification procedure from the high-molecular weight polymers. The oligomers have well-defined reactive end groups and are well suited for the preparation of high-molecular-weight block copolymers by chain extension. |
