Polymerization of 1-caprolactone had been investigated with cyclopentadienyl sodium as an initiator. The effects of reaction time, temperature, and concentration of the initiator on the yield and molecular weight of the polymer were discussed. It was shown that the high molecular weight of poly(1-ca
The polymerization of caprolactone ( 1-CL) was initiated by yttrium triisopropoxide {Y(OP i r ) 3 }, bimetallic isopropoxide of yttrium and aluminum {Y[Al(OP i s ) 4 ] 3 }, yttrium and tin(II) {Y[Sn(OP i r ) 3 ] 3 }, and tin(II) and yttrium {Sn[Y(OP i r ) 4 ] 2 }, respectively.
