Dihydrophilic block copolymers (DHBC) consisting of two water soluble blocks, are attractive templates to generate nanostructures in water. These molecules can self assemble into a range of morphologies by altering the media (pH, solvent quality, or temperature), or by altering the size of each block. A PAAMPSA-PEGMA DHBC was synthesized in two steps. First, PAAMPSA and PEGMA were polymerized via ATRP using either alkyne or azide functionalized initiators, next, the two homopolymers were combined using a copper-catalyzed 1,3 Huigens dipolar cycloaddition (CuAAC) to form the DHBC. The structure of the target polymers was confirmed by NMR, while the M.W. and PDI were obtained by GPC. The molecular weights ranged from 3kDa to 50kDa and the PDI's for the copolymers ranged between 1.2 and 1.3. Data on DHBC self-assembly in aqueous solution and its ability to serve as �nano-reactors� to produce metallic nanoparticles will be discussed.
