摘要：
Ring-opening polymerization Of D,L-lactide (LA) was catalyzed by the well-defined bis(trimethyl triazacyclohexane) praseodymium, triflate [(Me(3)TAC)(2)Pr(OTf)(3)] (Cat) for the first time. The effect of the [LA]/[Cat] molar ratio, solvents, temperature, and reaction time were investigated in detail. The results show that the praseodymium catalyst is very efficient in the melt polymerization, giving D,L-PLA with molecular weights of 10(4) in good conversion. The importance of the triazacyclohexane was shown by comparison to the poor catalytic activity of Pr(OTf)(3). (C) 2002 Elsevier Science B.V. All rights reserved.
