Abstract in another language

Sm(III) complex was generated in situ by one-electron transfer reaction of SmI2 with MMA. The resulting Sm(III) complex was tried as ring opening polymerization (ROP) initiator for cyclic esters like F-caprolactone (CL). The polymers were obtained in high yield with low polydispersity index (1.1-1.2). The system was also used for the synthesis of block copolymers. Structural characterization of the resulting polymers was done using ID (H-1, C-13, F-19) and 2D (H-1-C-13 heteronuclear multiple quantum correlation (HMQC) and heteronuclear rnultiple-bond correlation (HMBC)) NMR spectroscopic techniques.
