Need Help: Pyrolysis of Styrene-Butadiene Rubber (SBR)

[JOYCELIM]

Hi,
1. I know that Styrene-Butadiene Rubber (SBR) is a polymer, but i not sure what is the chemical formula, is it C12H14 or C36H42X2 or?
2. SBR can be pyrolysis into 1,3-Butadiene (C4H6) + Styrene (C8H8) + H2.
May i know how to balance the equation?

Formula can seen here.

At least the monomeres can be built back, but under alot of decomposition. There is no clear reaction.

I need to know the exact molecular formula of Styrene-Butadiene Rubber (SBR), because i need to write out all the equation of the pyrolysis of SBR to get fuel.
