Why is the viscosity of polystyrene sulfonate (PSS,70000 Da) very low and the viscosity of polyl-lactic acid with same molecular weight is high?

PSS (polystyrene sulfonate) viscosity.... Is it because of the charge of PSS (PSS is an ionomer)? How to explain the viscosity difference in terms of polymer structure? Thanks.
