Abstract :
It is conjectured that the mixing effects may be the noise that creates the broader variance in the composition data in the quality charts and the compositional distribution. A method is proposed to estimate the composition using the Weiner-Hopf integral equation. The composition of AN in the matrix is estimated from the QC chart and from the measured compositional distribution of the SAN copolymer formed in the reactor. This can then be used to predict the rotational speed of the agitator effect and to delineate the shear rate mechanism and mixing-blend time mechanism
