Palit and Das (Proc. Roy. Soc. London, 226A 82 (1954)) measured ῡtr at 60 ºC for different values of the ratio [SX]/[M] and evaluated CSX and ῡ for vinyl acetate undergoing chain transfer with various solvents. Some of their measured and derived results are tabulated below (the same concentrations of AIBN and monomer were used in each run). Assuming
that no other transfer reactions occur, calculate the values missing from the table. Criticize or defend the following proposition: The ῡ values obtained from the limit [SX]/[M] → 0 show that the AIBN initiates polymerization identically in all solvents.
