The flow behavior and viscosity of polymers are critical for understanding their structure and bonding, which directly impacts their processability into products such as plastics and elastomers. In a recent discussion, participants highlighted the significance of viscosity in determining molecular weight, particularly through experiments involving polystyrene dissolved in toluene. The relationship between viscosity coefficient (n) and molar mass (M) was established using the equation n = M^a, with 'a' approximately equal to 0.75. This research area remains vital for manipulating polymers for various applications.
