After optimization, we obtain the rate constant matrix and subsequently, the ternary reactivity Table shows the summary of the ternary reactivity ratios rounded to 3 decimal places, along with the binary reactivity ratio values obtained from the literature for comparison. While binary and ternary reactivity ratios are not interchangeable, binary reactivity ratios provide a good basis of comparison in assessing the magnitude of the ternary reactivity ratios. In general, all ternary reactivity ratios are of similar magnitude when compared to their binary reactivity ratio counterparts, except for 𝑟 32the ternary reactivity ratio between DBI and Myrcene. This implies that in a binary system of Myrcene and DBI, the propagating chain terminating in DBI prefers to add to a DBI monomer as compared to a Myrcene monomer, while in a ternary system of Styrene, Myrcene and DBI, the propagating chain terminating in DBI prefers to add to a myrcene monomer as compared to a DBI monomer, in the presence of the Styrene. This stands out as an outlier warranting further investigation which could be the subject of a further study. It is important to also note that the calculated ternary reactivity ratios could be influenced by experimental noise, which should be considered when interpreting the data. In the context of this study, the ternary reactivity ratios derived in the Styrene-Myrcene-DBI ternary system serves as useful information for polymer chemists who looking to study similar ternary systems.
