Abstract

We synthesized a new four-armed star-like hydrophobic associative polymer containing polyacrylamide core sections and poly(N,N-diethylaminoethyl methacrylate) CO2-switchable chain ends. The aqueous solution of the polymer is viscous due to formation of a network structure in the absence of CO2 but nonviscous in its presence. The viscosity also is enhanced with increasing concentration of NaCl.
