Effect of ionic liquids on the structural, thermal and in vitro degradation properties of poly(ε-caprolactone) synthesized in the presence of Candida antarctica lipase B
International audience The study provides detailed information on the differences in the structural, thermal and degradation properties of poly(ε-caprolactone) synthesized in two different ionic liquids, 1-butyl-3-methylimidazolium hexafluorophosphate [bmim][PF6] and 1-butyl-3-methylimidazolium bis(...
