Plastic bottlePolymer: High-density poly(ethene) (HDPE)
Catalyst allows polymerisation to occur at lower temperature and pressure

Plastic cratePolymer: isotactic poly(propene)
Close-packed chains produce strong polymer

Road paint (lines)Polymer: atactic poly(propene)
Loosely-packed chains produce softer polymer

Double-glazed window edgesPolymer: poly(chloroethene) (PVC)
No plasticiser produces a rigid polymer
