Molecular structure of the polymer matrix. PEO = polyethylene oxide; PPO = polypropylene oxide. b. Rheological studies of a triblock copolymer demonstrating reverse temperature dependent viscosity. As the temperature increases, the viscosity increases several orders of magnitude. Complex modulus in Pascals (Pa)Back to article page
