Green process for green materials: viable low-temperature lipase-catalysed synthesis of renewable telechelics in supercritical CO2Tools Curia, S., Barclay, A.F., Torron, S., Johansson, M. and Howdle, S.M. (2015) Green process for green materials: viable low-temperature lipase-catalysed synthesis of renewable telechelics in supercritical CO2. Philosophical Transactions A: Mathematical, Physical and Engineering Sciences, 373 (2057). pp. 1-16. ISSN 1471-2962 Full text not available from this repository.AbstractWe present a novel near ambient temperature approach to telechelic renewable polyesters by exploiting the unique properties of supercritical CO2 (scCO2). Bio-based commercially available monomers have been polymerised and functional telechelic materials with targeted molecular weight were prepared by end-capping the chains with molecules containing reactive moieties in a one-pot reaction. The use of scCO2 as a reaction medium facilitates the effective use of Candida Antarctica Lipase B (CaLB) as a catalyst at a temperature as low as 35 °C, hence avoiding side reactions, maintaining the end-capper functionality and preserving the enzyme activity.
