Overview
Polymers are large molecules formed by the repeated linking of small molecules called monomers. These materials are now an essential part of our daily lives, used in everything from plastic bags and clothes to medical devices and spacecraft. This chapter explores the science behind polymers, includi
Key Concepts
A monomer is a small molecule
A monomer is a small molecule capable of joining with others to form a polymer. A polymer is a high molecular mass compound made up of repeating monom
Addition polymerization involves monomers adding
Addition polymerization involves monomers adding to a growing chain without losing atoms, typically from unsaturated compounds like ethene. Condensati
A homopolymer is made from one
A homopolymer is made from one type of monomer, such as polythene. A copolymer is formed from two or more different monomers, like Buna-S (from butadi
Polymers are categorized into elastomers (rubber
Polymers are categorized into elastomers (rubber-like, stretchable), fibers (strong, thread-forming), thermoplastics (soften on heating), and thermose
These are polymers that can be
These are polymers that can be broken down by microorganisms into harmless substances. Examples include PHBV, PGA, PLA, and PCL. They are designed wit
