For moderate or high conversion copolymerization data three sorts of peculiar data points are discussed which are disadvantageous in determining the relative reactivity ratios: (a) copolymer contains an unknown quantity of homopolymer because the comonomer was fully consumed before the end of the reaction, (b) estimation error of the conversion is relatively high, (c) estimation error of the copolymer...
The numerical integration method was developed to determine the relative reactivity ratios according to the simplified penultimate model (systems with r 2 = 0). It allows one to calculate the copolymer composition for zero conversion level. This procedure was used to verify the Walling-Briggs method. For this purpose literature data for the monomer system styrene/methyl α-cyanocinnamate...
