bonding in polymers Flashcards
1
Q
what are polymers made by?
A
joining together thousands of small, identical molecules (monomers)
2
Q
what are monomers?
A
they’re often alkene molecules (eg ethene)
3
Q
what do polymers contain?
A
single carbon to carbon covalent bonds
4
Q
what does a repeating unit contain?
A
- single covalent bonds
- bonds expand out of the bracket
- the n tells us the polymer contains a large number of repeating units joined together
5
Q
what are polymers at room temp?
A
solids
6
Q
why are polymers solids at room temp?
A
because the intermolecular forces between polymer molecules are relatively strong
