Polymerizations of spiro left bracket 2,4 right bracket hepta-4,6-diene were carried out with cationic initiators and Ziegler-type catalysts. This monomer polymerized very rapidly with a variety of cationic initiators, and low monomer and initiator concentrations had to be employed in order to avoid formation of crosslinked polymers. The polymer contained 1,2 and 1,4 addition units, and there was no indication of the opening of the cyclopropyl ring in the monomer unit.
