Cyclic oligomers obtained by polymerizat

The reaction of 2,2-dimethyltrimethylene carbonate (DTC) and E-caprolactam (EClam) in toluene with s-BuLi as initiator leads to cyclic oligomers containing one EClam moiety and n DTC units (n = 2-10). A mechanism for the formation of the oligomers is proposed.
