C2 : Bonding in Polymers Flashcards
1
Q
Polymers
A
Polymers are made by joining together thousands of small, identical molecules (monomers)
(monomers are often alkene molecules e.g. ethene)

Q
Why are most polymers solids at room temperature
A
Because the intermolecular forces between the polymer molecules are relatively strong
(they take a lot of energy to break) so polymers have a high melting point
