6-tetramethyl-4-piperidinyl methacrylate (TMPM) with styrene has been studied in various solvents: benzene
chlorobenzene
pyridine
dimethyl formamide and petroleum ether. The reactivity ratios were calculated by the linear graphical method of Kelen-Tudos. It is observed that in all these systems there is a marked solvent effect on both r1 and r2
which can be correlated to the difference in chemical shifts of β-olefinic protons of TMPM.
