Being combining with products distribution in styrene oxidation, we propose the styrene epoxidation carry out with Ti metallacyclo intermediates, And at the same time Ti-ZSM-5 have properties both catalytic epoxidation and acid-catalysis, namely the skeletal Ti can catalyze styrene epoxidation to styrene oxide and the skeletal Ti and Al can provide Lewis acid site to cause the rearrangement of styrene oxide to phenylacetaldehyde rapidly, the solvolysis to glycols and the cleavage of C=C double bond. Ti-ZSM-5 can also provide Bronsted acid site simultaneously, which is also catalytic center for the solvolysis to glycols.

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.
