anyone know why polymers have higher melting points than other simple molecules?

I would assume it’s because they tend to have such long chains. The length allows for tangling and more interactions along the length, requiring more energy to pull them apart.

Not sure on the exact answer your examiner would be looking for depending on the level you’re at though!

Being simple molecules, polymers are bonded by Van der Waal forces, which are dependent on the size of the molecule. Because polymers are made of larger molecules than ordinary simple molecules the Van der Waal forces are stronger in polymers than other simple molecules, so more energy is required to break the bonds in polymers.
