34. The catalysis by the salen-zinc complexes proceeds via the thermal dissociation of hemiacetal ester to produce the corresponding carboxylic acid that nucleophilically attacks epoxides predominantly over the thermally dissociated vinyl ether. Salen-zinc complexes catalyze both the dissociation of hemiacetal ester to produce the carboxylic acid intermediate and its addition to epoxide; see also Ref. 23.
35. Because a catalyst active site exists in Polyurethane main chain, kineticism might be bad. In particular, there might be existed the high active structure at low temperature, since it is hard to become the stability structure in thermodynamic.
