Chapter 8) Polymers and Society

Polymers

Long chains formed from simpler molecules called monomers that undergo various reactions to link together and create a polymer.

Addition Polymerisation 1 monomer

Process where monomers with double bonds (alkenes) break the bond to allow the addition of the next monomer unit.

Condensation Polymerisation 2 different monomers

Formation of polymers through a condensation reaction where monomers join, releasing small molecules as byproducts.

Thermoplastic

Plastics that can be reheated, remolded, and cooled, formed by an addition reaction.

Thermoset

Plastics that cannot be remolded, do not melt, and char, formed by a condensation reaction.

Polymer Selection

Influenced by the choice of monomer, degree of branching, and degree of crystallinity.

Plasticisers

Additives that soften and increase flexibility in polymers.

Biodegradability

The capacity of a material to be broken down into simple molecules like carbon dioxide and water.

Circular Economy

Recycling options including mechanical, chemical, and organic methods to reuse polymers.
