Synthesis and Rheology of Model Comb Polymer Architectures

For a better understanding of the extent of branching and its influence on the rheological properties of commercial branched polymers, well-defined linear and branched (comb) model polymers were synthesized. The correlation between the melt rheological properties and the polymer topology was investigated under small amplitude oscillatory shear (SAOS), uniaxial extension and medium- (MAOS) respectively large amplitude oscillatory shear (LAOS) in combination with Fourier-Transform rheology
