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
A novel 5'-deoxy-5-fluorouridine-poly(epsilon-caprolactone) (5'-DFUR-PCL) polymer was synthesized from the antitumor agent doxifluridine (5'-DFUR) by the ring-opening polymerization of epsilon-caprolactone (epsilon-CL) using Sn(II) 2-ethylhexanoate (Sn(Oct)2) as the catalyst. The structure and molec
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. The polymerization wa
