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

Table 3

Analysis of variance results of the model of polymer pressure p, where the coefficient of determination and its corrected value are equal to R²≈ =0.96. 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.
