Donald J. Darensbourg,* Poulomi Ganguly, and Damon Billodeaux: Ring-Opening Polymerization of Trimethylene
Carbonate Using Aluminum(III) and Tin(IV) Salen Chloride Catalysts.Volume 38, Number 13, June 28, 2005, pp 5406-5410. In Table 5 the rate constants should be listed as kobsd in units of h-1. Similarly, Figure 7 should be defined as a plot of ln kobsd vs ln[Al], illustrating the first-order dependence of the ROP process on the (salen)AlCl catalyst concentration. Figure 8 should be replaced with the figure below, which provides activation parameters for the ROP of trimethylene carbonate by (salen)AlCl of ∆Hq ) 51.4 ( 3.2 kJ/mol and ∆Sq ) -105 ( 8.4 J/(mol K).
Figure 8. Eyring plot of temperature dependence of second-order rate constant with an R2 value of 0.985.
