- Polymers
- poly = many, mers = parts
- Alkenes used to make polymers as they have double bonds. Alkanes don't.
- Made up of monomer units.
- Low density poly(ethene) makes stuff like clingfilm and plastic bags.
- It has weak intermolecular forces (easily broken)
- To make: high pressure, and a trace of oxygen.
- High density poly(ethene) makes bottles and storage tubs.
- Strong intermolecular forces.
- To make: low pressure and a catalyst at 50 degrees.
- Thermosoftening polymer.
- Tangled web easily broken due to WIF.
- Thermosetting polymer.
- Cross linked, bonded to each other.
- Strong intermolecular forces.
