Example 3.5 Estimate the chain transfer constants for styrene to isopropylbenzene, ethylbenzene, toluene, and benzene from the data presented in Figure 3.6. Comment on the relative magnitude of these constants in terms of the structure of the solvent molecules. 200 150 Isopropylbenzene Ethylbenzene Toluene No X105 100 32 1 Benzene 50 10 20 30 [SX]/[M] Figure 3.6 Effect of chain transfer to solvent according to Equation 3.8.8 for polystyrene at 100C. Solvents used were ethylbenzene (6), isopropylbenzene (O), toluene (A), and benzene (O). (Data from Gregg, R.A. and Mayo, F.R., Discuss. Faraday Soc., 2, 328, 1947. With permission.)
