Polymer basics🔸
- Polymers are covalently bonded materials known for their low thermal and electrical conductivity, and low density compared to other types of materials.
- They are macromolecules, which are very large molecules.
- Examples of synthetic polymers: plastics and synthetic textiles like nylon.
- Examples of natural polymers: fibrous materials like lignin and silk, as well as biological molecules involved in life processes, such as DNA, starch, and proteins.
Monomers & polymerization🧪
- Polymers are made up of long, covalently bonded chains. The small molecules that combine to form these chains are called monomers.
- The process of joining monomers together to create a polymer chain is called polymerization.
- Imagine monomers as beads; when you string these beads together, you create a necklace. Similarly, polymerization is like creating a necklace of monomers.
- There are two types of polymerization: addition and condensation.
Real - world examples🌈
- DNA: The blueprint of life is a natural polymer! DNA is made up of nucleotide monomers that join together to form a long chain that carries genetic information.
- Plastic Bottles: Polyethylene terephthalate (PET) is a common polymer used to make plastic bottles. It is formed by the polymerization of ethylene glycol and terephthalic acid.
- Nylon: This synthetic polymer is used to make everything from stockings to parachutes! It is created by polymerization of a type of monomer called an amide.
- Starch: Found in foods like potatoes, starch is a natural polymer made up of glucose monomers.
- Proteins: Essential for our bodies, proteins are natural polymers formed by the polymerization of amino acid monomers.
