This is not easy to answer, because it depends on temperature, pressure and probably catalyst additives.

Generally you can develop from the monomeres styren C6H5-CH=CH2 and Butadien CH2=CH-CH=CH2 the compound what you wish to have.

C8H8 => 4 C2H2

C8H8 => 2 CH4 + 6 C

C4H6 => C2H2 + C2H4

C4H6 => C2H6 + 2 C etc.
