4, the terpolymerization model differs for each data set: low conversion data are analyzed using the recast instantaneous terpolymerization model (Equation (2)) along with the related low conversion assumptions, whereas the medium-high conversion data are analyzed with the direct numerical integration (DNI) of the instantaneous model, i.using the cumulative composition model (see Equations (2), (4) and (5)).
The terpolymerization reactivity ratio estimates and corresponding JCRs for both data sets ( Table 2 and Table 3 ), along with the corresponding binary (copolymerization) reactivity ratios ( Table 1 ) are presented in Figure 3.
In all cases, the results show that JCRs from medium-high conversion data are smaller (and therefore more precise) than JCRs from low conversion data.
These results are as expected; utilizing all of the experimental information available and eliminating potentially inaccurate assumptions can improve the precision of the point estimates.
