✦ Synopsis

The initiation rate constant and the composition of copolymers formed at 50 in St--BA-AIBN-Bz systems of various compositions were investigated. The initiation rate constant was linearly dependent on the composition of monomers ("additive behaviour"). The experimental composition data were evaluated by the r/-¢ transformation method and the reactivity ratios determined accordingly are dilution independent values: p~ = 0.698 -0.033, p, = 0.164 + 0.017.
