Section 7 - Polymerisation Flashcards
Alkenes can form polymers. Why is this?
Due to the presence of the double bond in alkene molecules
What is a polymer?
A long, chain-like molecule built up from lots of repeating units.
How do alkenes form polymers?
Under the right conditions (these depend on the alkene and the desired properties of the polymer), many small alkenes (like ethene and propene) will open up their double bonds and link together to form these long chain polymers.
What polymer can propene form?
Polypropene
What polymer can styrene, which has a benzene ring in it, polymerise to form?
Polystyrene
What is benzene?
A ring of six carbon atoms in which the bonding electrons are shared between all six carbons
