2. 1. Novel methods to synthesize aliphatic polyesters of vivid architectures

   Author : Rajiv Srivastava; Ann-Christine Albertsson; Ronnie Palmgren; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polyesters; 1; 5-dioxepan-2-one; Caprolactone; Sn Oct 2; Enzyme; Lipase-CA; Ring-Opening Polymerization; Architecture; Tissue Engineering; Polymer chemistry; Polymerkemi;

   Abstract : Cross-linked films of ε-caprolactone (CL) and 1,5-dioxepan-2-one (DXO) having various mole fractions of monomers and different cross-link densities were prepared using 2,2’-bis-(-caprolactone-4-yl) propane (BCP) as cross-linking agent and Sn(Oct)2 as catalyst. Reaction parameters were examined to optimize the film-forming conditions. READ MORE
