Abstract

A newly developed method for the determination of the radical reactivity ratios is presented. Two main equations are used and the parameters can be calculated from the ordinate and the slope of the linearization plots. Both equations yield identical values when applied to synthetic data which conforms to the ideal situation of no error in the input data. As experimental data are always subject to some kind of error, a sensitivity analysis was carried out which took into account a relatively pronounced error in the monomer reactivity ratios. It turned out that the new linearization method may even be indicative of the quality of the input data under favorable conditions.

## Abstract Summary: In copolymerization systems with implicit penultimate effect, there are two radical reactivity ratios, __s~a~__ and __s~b~__, which influence the reaction kinetics in addition to the monomer reactivity ratios, __r~a~__ and __r~b~__, which govern the copolymer composition. Here,

## Abstract The present study reports values of reactivity ratios for ethylene/1‐hexene, ethylene/1‐octene and ethylene/1‐decene copolymerizations promoted by C~2~H~4~[Ind]~2~ZrCl~2~/MAO. The comonomer reactivities are markedly influenced by the number of carbon atoms of the α‐olefin. The ethylene/
