Scholarcy highlights

  • Thermoresponsive amphiphilic poly(hydroxyl propyl methacrylate)-b-poly(oligo ethylene glycol methacrylate) block copolymers are synthesized by RAFT polymerization, with different compositions and molecular weights
  • The copolymers are molecularly characterized by size-exclusion chromophotography, and 1H NMR spectroscopy
  • Aggregate structural characteristics depend on copolymer composition, molecular weight, and ionic strength of the solution
  • Fluorescence spectroscopy experiments confirm the presence of less hydrophilic domains within the aggregates at higher temperatures
  • The thermoresponsive behavior of the PHPMA-b-POEGMA block copolymers is attributed to the particular solubility characteristics of the hydrophilic, water insoluble PHPMA block that are modulated by the presence of the water soluble POEGMA block
