Polymer Products

Polymer: Low-density poly(ethene) (LDPE) Plastic bag Polymer: Low-density poly(ethene) (LDPE) Polymerisation at high temperature and pressure

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

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

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

Polymer: poly(vinyl chloride) (PVC) or low-density poly(ethene) (LDPE) Cling film Polymer: poly(vinyl chloride) (PVC) or low-density poly(ethene) (LDPE) Plasticiser and extremely thin sheets produce stretchy, clingy material

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

Electrical cable insulation Polymer: poly(chloroethene) (PVC) Addition of plasticiser produces a flexible polymer
