The radical copolymn. of poly(St-b-EO)-MA macromer (I) with St
MMA
MA(M2) has been studied in various solvents: benzene
THF
DMF. The reactivity ratios (r2) were calculated by the Kennedy's equation. It is observed that in all these systems there is a marked solvent effect on In(1/r2)
which can be correlated to the different dielectric constants (ε) and to the difference between solubility paremeter of growing active chain and that of solvents.
