Polymers

There are many natural polymers including latex, cellulose (from ____________) and cotton.

rubber (another natural polymer) for solid tyres on an early bicycle

Familiar plastics uses today: polyethene, polystyrene, PVC and nylon. Man-made polymers (synthetic polymers) have a huge range of properties and uses, and are often referred to as plastics. Familiar plastics uses today: polyethene, polystyrene, PVC and nylon. Source: BigStockPhoto.com (© Colin and Linda McKie, © Nguyen Thai, Simon Krzic, © Freddie Thompson)

Polymers used in a variety of everyday items.

Polymers are made of long chain molecules. Milk contains casein, a protein (natural polymer). We can make a plastic from milk!
