Candidates
Intermediate Candidates
Ethylene
C₂H₄- Chemistry role
- The simplest alkene: light, simple, and a foundational petrochemical monomer.
- Character design
- A tiny sprinter: honest, fast, and ready to run into many routes.
- Main routes
- PE / EG / PVC route / styrene route
Propylene
C₃H₆- Chemistry role
- A branched step beyond ethylene, feeding PP, acrylic, oxo, and related routes.
- Character design
- A quick route-switcher with compact energy and fast branching decisions.
- Main routes
- PP / acrylic chemistry / oxo route / PU-related
Butadiene
C₄H₆- Chemistry role
- A conjugated diene with two double bonds, central to elastomers and ABS-related routes.
- Character design
- A spring-loaded athlete: elastic, tough, and always rebounding.
- Main routes
- BR / SBR / NBR / ABS
Benzene
C₆H₆- Chemistry role
- The fundamental aromatic ring: stable, planar, symmetrical, and central.
- Character design
- A calm theorist who holds the ring together with quiet symmetry.
- Main routes
- styrene / phenolic resin / aromatic intermediates
Toluene
C₇H₈- Chemistry role
- Methylated benzene: aromatic, practical, mobile, and solvent-like.
- Character design
- A freckled route scout moving samples between theory and plant work.
- Main routes
- solvents / TDI-related / aromatic routes
Xylene
C₈H₁₀- Chemistry role
- An isomer family where separation, comparison, and p-xylene routes matter.
- Character design
- A bespectacled planner sorting three routes with quiet precision.
- Main routes
- p-xylene / terephthalic acid / PET
Styrene
C₈H₈- Chemistry role
- An aromatic-vinyl bridge leading toward PS, ABS, and SBR.
- Character design
- A model-club maker: light, formable, creative, and a little fragile.
- Main routes
- PS / ABS / SBR
Vinyl Chloride
C₂H₃Cl- Chemistry role
- A chlorinated vinyl monomer whose PVC route demands sealed handling.
- Character design
- A strict safety monitor protecting the class through disciplined handling.
- Main routes
- PVC
Acrylonitrile
C₃H₃N- Chemistry role
- A polar nitrile monomer for ABS, NBR, and acrylic fiber routes.
- Character design
- A cool technical ace handling high-performance routes with precision.
- Main routes
- ABS / NBR / acrylic fiber
