Which mechanism causes increased solvent viscosity with elevated molecular concentrations of polymers?

💡 Explanation

Elevated concentrations cause increased viscosity because polymers form chain entanglements due to limited space. This entropic chain entanglement restricts their mobility, therefore viscosity increases rather than remains constant like in less viscous solutions.
