Polycaprolactone-based block copolymers. I - Synthesis by anionic-coordination type catalysts

[en] Bimetallic µ-oxalok oxides are very active anionic coordination type catalysts in the living polymerization of t-caprolactone. These compounds have a well-defined composition which can be systematically modified. It is proposed that at least half the alkoxy groups of these catalysts are replaced by carboxylate ones and the remaining alkoxy groups by any hydroxyl-terminated polymer PX. These new polymer PX-supported catalysts are powerful tools in tailoring poly(ε-capro1actone) block copolymers with well controlled molecular parameters.
