Polymers (HSC SSCE Chemistry): Flashcards

Small building-block molecules that link to form polymers

Chemical process connecting monomers into long chains

Soften and can be melted/remoulded; recyclable

Don't soften; cross-linked structure prevents remoulding

Polyethylene, PVC, PET

Polyurethane, melamine, Bakelite

Ethylene (ethene), formula $\text{C}_2\text{H}_4$

~500°C, 4-20 atm, zeolite catalysts

~700°C, up to 70 atm, no catalyst

Environmental persistence & crude oil dependency
