Title: | Anionic flow polymerizations toward functional polyphosphoesters in microreactors: Polymerization and UV-modification | Authors: | BAETEN, Evelien Vanslambrouck, Stephanie Jerome, Christine Lecomte, Philippe JUNKERS, Tanja |
Issue Date: | 2016 | Publisher: | PERGAMON-ELSEVIER SCIENCE LTD | Source: | EUROPEAN POLYMER JOURNAL, 80, p. 208-218 | Abstract: | The polymerization of cyclic phosphates to poly(phosphoester)s, PPEs, is optimized for chip-based microreactors under continuous flow conditions. The anionic ring-opening polymerization of 2-isobutyoxy-2-oxo-1,3,2-dioxaphospholane (iBP) via the use of two organocatalytic systems allowed to polymerize to nearly quantitative monomer conversion within 10 or 3 min, respectively at a reaction temperature of 40 degrees C. Further, the optimized polymerization protocol was applied to 2-butenoxy-2-oxo-1,3,2-dioxaphospholane (BP) which yields a polymer that carries an alkene functionality per monomer repeating unit. This material can be postmodified in an UV-induced radical thiol-ene reaction, which was also shown to proceed with very high efficiency under UV-flow conditions. Eventually, both reactions were coupled in a two-stage reactor setup, showing that the thermally-activated polymerization can be coupled with high efficiency to the UV-activated post-polymerization modification reaction. The introduced reactor setup can in the future be used to produce and screen a broad variety of functional PPE materials with various functionalities and physical properties. (C) 2016 Elsevier Ltd.
