A
Polymers are long-chain molecules formed by joining many small, repeating units called monomers held together through chemical bonds. They can be natural (like proteins and rubber) or synthetic (like plastics).
2
Q
What are plastics?
A
Plastics are common examples of synthetic polymers, used widely in everyday products.
3
Q
What is addition polymerisation?
A
Addition polymerisation is a chemical reaction where unsaturated monomers (with C=C double bonds) join together through an addition reaction to form a polymer.
4
Q
What is a monomer?
A
