The closest thing to a diamer is the polymer inside dipers that absorbs urine. It sounds like a joke but it's not.

Have a look at:

Who said they evaporate?
Evaporation of very big molecules is very tough and that's why it is not so easy to do Mass Spec of big proteins. However difficult doesn't mean impossible...

If you meant dimers then it's something completely different and as the previous answer points out there are lots of small dimers.

Well what's a polymer? Polymer is a term used to describe molecules consisting of structural units and a large number of repeating units connected by covalent chemical bonds. Ploy means "many".

So... what's a dimer? (by the way, it's dimer, not diamer. That's probably why, if you searched, you can't find anything about it).

If poly = many, then di = two. It's a molecule composed of two similar subunits or monomers linked together.

Now are you asking why large moleclues can evaporate? Keep in mind that no matter how big a molecule is (save carbon strings), it's going to have very little mass! If it's a liquid, it can evaporate if you get it hot enough. Adding kinetic energy to the molecules will make them separate and turn into a gas. It will have the properties of gases, and will have no definite volume.

By the way, not all dimers are big. They can be, but sometimes not.

Oh, and let Wikipedia be your guide.
