Polymers (A-level only)
Key terms
Addition Polymerisation
A chemical reaction where monomers join together to form a polymer without the loss of any small molecules.
Condensation Polymerisation
A chemical reaction where monomers join together to form a polymer with the loss of small molecules, often water.
Monomer
A small molecule that can join together with other monomers to form a polymer. In Polymerisation and polymer properties (A-level only), Monomer is used to explain identify addition and condensation polymerisation reactions with A-Level Chemistry precision.
Polyester
A type of polymer formed from the condensation reaction between a diol and a dicarboxylic acid, characterized by ester linkages.
Polyamide
A type of polymer formed from the condensation reaction between a diamine and a dicarboxylic acid, characterized by amide linkages.
Monomer
A small, simple molecule that can join together with other monomers to form a polymer. In Polymerisation and polymer properties (A-level only), Monomer is used to explain draw repeating units and monomers for polyesters and polyamides with A-Level Chemistry precision.
hydrolysis
A chemical process that involves the breaking down of a compound by reaction with water. In Polymerisation and polymer properties (A-level only), hydrolysis is used to explain explain hydrolysis of condensation polymers with A-Level Chemistry precision.
condensation polymer
A polymer formed through condensation reactions, where monomers join together with the elimination of small molecules, often water.
repeating unit
The specific arrangement of atoms that repeats in a polymer chain, representing the structure of the polymer.
biodegradable polymer
A polymer that can be broken down by microorganisms into natural substances. In Polymerisation and polymer properties (A-level only), biodegradable polymer is used to explain discuss disposal and biodegradability of polymers with A-Level Chemistry precision.
non-biodegradable polymer
A polymer that cannot be easily broken down by microorganisms and persists in the environment.
polymer disposal methods
Techniques used to manage and eliminate polymers, including recycling, incineration, and landfill.
