Abstract
AbstractA novel ytterbium (II) complex 2 supporting by a bridged bisphenolate ligand H2LOC4H7 (L = C4H7OCH2N(CH2‐2‐OC6H2‐3,5‐Bu)2) with a tetrahydrofuran donor on side‐arm was synthesized in high yield and characterized by elementary analysis, IR, 1H‐NMR, and 13C‐NMR. Ring‐opening polymerization of 1,3‐trimethylenecarbonate (TMC) was carried out using complex 2 and a known complex [Me2NCH2CH2N(CH2‐2‐O‐3,5‐C6H2(But)2)2]Yb 1 as the initiators, respectively. It was found that both complexes 1 and 2 can alone initiate the ring‐opening polymerization of TMC, and complex 1 showed higher activity than complex 2. The activity of both complexes 1 and 2 was found to be higher than that of monodentate phenoxo ytterbium (II) complex (2,6‐Bu‐C6H3O)2Yb(THF)3. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
