Those polymers usually contain hydrophobic and hydrophilic blocks, which allow them to undergo self-assemby in aqueous solution. Thermally-responsive amphiphilic copolymers have been investigated by our group. Thermally-responsive blocks which have a lower critical solution temperature (LCST) will become insoluble in aqueous solution upon heating and induce the morphological changes in copolymer assembly. In this project, amphiphilic tri-arm star copolymer which contains one hydrophilic polyethylene glycol (PEG) block, one hydrophobic polylactide (PLA) block and one thermally-responsive Poly(N,N-diethylacrylamide) (PDEAm) block with a LCST at 30 \u00b0C have been synthesized. A mPEG-S(BOC)-OH macroinitiator was used to initiate ring-opening polymerization of lactide to afford diblock mPEG-S(BOC)-PLA. After successful removal of BOC protecting group, N-acryloxysuccinimide (NASI) was used as the linking agent to connect the diblock PEG-S(NH2)-PLA with a thiol-terminated PDEAm block prepared by reversible addition-fragmentation chain transfer (RAFT) polymerization. The thermally-responsive behavior of the copolymer will be studied with dynamic light scattering (DLS)."},{"label":"dcterms.available","value":"2017-09-20T16:51:59Z"},{"label":"dcterms.contributor","value":"Bhatia, Surita"},{"label":"dcterms.creator","value":"Jiang, Menglan"},{"label":"dcterms.dateAccepted","value":"2017-09-20T16:51:59Z"},{"label":"dcterms.dateSubmitted","value":"2017-09-20T16:51:59Z"},{"label":"dcterms.description","value":"Department of Chemistry."},{"label":"dcterms.extent","value":"41 pg."},{"label":"dcterms.format","value":"Monograph"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/11401/77113"},{"label":"dcterms.issued","value":"2014-12-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Made available in DSpace on 2017-09-20T16:51:59Z (GMT).
