What are synthetic polymers and what are some examples?
Man-made polymers such as nylon, polyester, teflon and epox.
Give some examples of natural polymers
Nature-bound:
silk, rubber
Biological molecules
DNA and proteins
What are Monomers?
Small units that repeat along a polymer chain, forming the polymer.
Repeating unit
A group of atoms that appears repeatedly along a polymer chain.
Tell me about polymers
a class of covalently bonded materials characterized by their low thermal and electrical conductivity and low density compared to other materials.
They are macromolecules. They are long, chain-like molecules that are built from smaller molecules called monomers.
Tell me about Polymer Properties
stable
require large amounts of energy to break
not electrically conductive.
What are Plastics?
Synthetic polymers composed mainly of carbon and hydrogen.
Tell me about Plastics’ properties
non-reactive due to their strong bonds.
hard to break down and very durable.
not biodegradable
What is problematic about Plastics? How does it affect the environment?
The process of plastics involves energy-intensive sorting and cleaning.
Discarded plastic products often end up in landfills or the ocean, causing harm to the environment.
