Polymerization of cyclohexene oxide with Al(acac)3‐ silanol catalyst
1981
The polymerization of cyclohexene oxide was investigated with a new catalyst system of Al(acac)3- silanol compounds. Catalyst activity varied with the ratio of silanol/Al(acac)3 and the structure of silanol compounds. Catalyst deactivation appeared to be caused by self-condensation of silanol and the addition of silanol to the epoxy ring. Polymer structure was investigated by 13C-NMR spectroscopy and x-ray diffraction. The mechanism of the polymerization appears to be cationic.
