Abstract

The ring-opening polymerization (ROP) of -caprolactone (-CL), 4-methyl--caprolactone (4-MeCL), and 6-methyl--caprolactone (6-MeCL) with a single-site chiral initiator, R,R-(salen) aluminum isopropoxide (R,R-[1]), was investigated. The kinetic data for the ROP of the three monomers at 90° in toluene corresponded to first-order reactions in the monomer and propagation rate constants of k-CL > k4-MeCL k6-MeCL. A notable stereoselectivity with a preference for the R-enantiomer was observed in the ROP of 6-MeCL with R,R-[1], whereas for 4-MeCL, no stereoselectivity was found
