The results show that both norbornenic and cyclopentenic double bonds are involved in the polymerization. The propagation on the NB double bond generates structural unit I by direct addition and unit II by carbocation rearrangement, respectively. Similarly, the propagation on the CP double bond produces structural unit III by direct addition and unit IV by transannular rearrangement, respectively.
