Polymerization of ε-Caprolactone and Lactide with Rare Earth Acetylacetonates

Department of Polymer Science and Engineering, Zhejiang University, Hangzhou 310027

Received Date: 27 December 1994
Revised Date: 3 May 1995

It is found that rare earth acetylacetonates can initiate the ring-opening polymer-ization of ε-caprolactone and lactide. The effects of temperature solvent,polymerization time,rare earth element and ligand were studied. The results showed that rare earth acety-lacetonates,particularly Y(acac)₃,were good catalysts for the polymerization of ε-caprolac-tone and lactide. Crystalline polycaprolactone with viscosity-average molecular weight of 1.4 × 10⁵ could be obtained at 80℃ in quantitative yield.
