Topic 9 - Plastics Flashcards
(6 cards)
What are plastics?
examples of materials known as polymers.
What are polymers and how are they formed?
they are long chain molecules formed by joining together a large number of small molecules called monomers.
What is addition polymerisation?
the name given to a chemical reaction in which unsaturated monomers are joined, forming a polymer.
What is a repeating unit?
the shortest section of polymer chain which, if repeated, would yield the
complete polymer chain (except for the end-groups).
What can you draw the structure of a polymer with?
The structure can be drawn given either the structure of the monomer or the repeating unit.
What can you draw from the structure of a polymer?
the monomer or repeating unit
