Effect of pressurized CO2 and N2 on the rheology of PLA

[Display omitted] •PLA viscosity during assisted melt-extrusion processing was successfully evaluated.•PFAs are more effective to plasticize PLA than conventional bio-based ATBC.•Addition of 1.7 wt% CO2 allows reducing 10 °C the processing temperature.•N2 produces the highest plasticization effect,...
