Thesis: Amphiphilic block copolymers containing polysaccharides and synthetic polymer units

Abstract: Polymers containing polysaccharide and synthetic polymer units (i.e., glycopolymers) having amphiphilic character were explored.   A multitude of polymer chemistries were used to create these glycopolymers, including Atom Transfer Radical Polymerization (ATRP), Single Electron Transfer Living Radical Polymerization (SET-LRP), and cobalt(II) mediated Catalytic Chain Transfer Polymerization (CCTP).   In addition, thiol-Michael addition and reductive amination chemistries were used as intermediate steps in the synthesis of some synthetic-natural polymer hybrids.   The architecture of these glycopolymers   (i.e., graft, linear, or hyperbranched) was explored as a means to produce amphiphilic materials with controllable colloidal stability in water.   These materials could be used in environmental or drug delivery applications or as modified degradable polymers for commercial use.
