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