Synthesis of aliphatic polyesters of various architectures by the controlled ring-opening polymerization of cyclic esters
Polimery 2002, No 7/8, 469
A review covering 80 references presents recent studies on the controlled synthesis of poly(aliphatic ester)s (PAE's), mostly including poly(ε-caprolactone) and poly(L-lactide). In the introduction, general features and practical applications of PAE's, the latter resulting mostly from ability of these polymers to (bio)degradation, are briefly discussed; polymerization methods leading to PAE's are also presented. Then, the ring-opening polymerization of ε-caprolactone (CL) and L,L-dilactide (LA), including thermodynamic and kinetic polymerizability of CL and LA is described. Finally, recently elaborated methods of synthesis, of poly(ε-caprolactone)s and poly(L-dilactide)s of various architectures, such as linear homopolymers, and star-shaped polymers are presented in a more detail.
