Description
Summary:This paper demonstrated the feasibility of conducting an enzymatic ring-opening polymerisation by reactive extrusion (REX) at high shear and temperature conditions. Using immobilized Candida antarctica Lipase B (CALB) as catalyst at temperatures ranging from 90 to 130 °C, ω-pentadecalactone (PDL) was converted (>99%) by REX at 60 RPM for 15 min to PPDL with ≥ M w 163 000 g mol −1 . Enzyme catalysed ring-opening polymerisation was performed by reactive extrusion gave high molecular weight polyester ( M w ≥ 163 000 g mol −1 ) in 15 minutes.
