Effect of the Intensive Plasticizing Zone Design on the Effectiveness of Corotating Twin-Screw Extrusion

Table 4

Analysis of variance results for the model of polymer mass flow rate G, with the coefficient of determination and its corrected version equal to R²≈ =0.98. SS: sum of squares, df: number of the degrees of freedom, MS: mean sum of squares, F: values of the test statistic, p: value of probability corresponding to the test statistic value.
