Many polymer chemists still use unreliable and outdated methodologies to obtain reactivity ratios, including poor experimental design, incorrect statistical procedures, and failure to account for uncertainties in the experimental data. There is thus a clear need for a standardized, easy to implement and unbiased method for the determination of reactivity ratios in copolymerization.
The objective of this recently initiated project is to outline robust methodologies to determine reactivity ratios, combining experimental procedures with correct data evaluation. The methodologies are mainly focused on the terminal model, but model discrimination is also included. The emphasis is on proper design of experiments, error estimation of the obtained data, validity test of the model applied, followed by correct statistical reactivity ratio estimation.
