Yes. They are called polymers. But they are very old, since plastic originated in the mid-late 1800's. But we are discovering new polymers to this day.

Why is the boiling point of butanone higher than pentane?
Butane is a smaller molecule, so the London Dispersion forces between molecules of butane hold the molecule together better than the London Dispersion forces of a hexane molecule. In short, it requires more energy to separate butane molecules from each other than hexane molecules.
How atoms combine to make a bond?
Atoms combine together to form molecules. In molecules the consitutent atoms are held together by attractive forces. This attractive force which binds the atoms in a molecules is called as bond.
Water molecules stick to other substances?
its all polar. The molecules are made up of two hydrogen and one oxygen molecule. They arrange themselves in a assymetrical way. This causes the molecule to have a different charge at one end than the other, so the molecules are attracted to one another. That's the short answer, depending on how specific you need there is probably and really specific definition on wikipedia, just read about the physical properties of the water molecule, it is a quite interesting and unique molecule.Also called cohesion.
Why doesn't carbon exist as a single molecule?
Carbon exists both as atomic carbon (a single carbon atom) and as carbon molecules (Fullerenes) The atomic carbon is a very short lived species. The Fullerenes (like Buckey Balls) are very stable.
Are Molecules closer together in gases than in liquids?
The molecules in a solid are held together by short invisible bonds. A way to think about these bonds is that they slowly stretch as they move towards gas form. So in a solid the bonds are stronger and shorter, without them being held in such close proximity to each other they wouldn't be able to hold there shape, resulting in a more liquid form. Now in short, it is so the invisible bonds can more easily control the molecules in the object.

What is the result of intermolecular forces being repulsive and attractive at varying distance?
Hydrogen bonds
What is the result of intermolecular forces being repulsive and attractive varying distances?
Once molecules become close enough to touch, intermolecular forces become repulsive. This is what prevents one molecule from overlapping another. Intermolecular forces pull molecules together at a long range and hold them apart at short range.
Which of the following is true regarding complementary base pairing in DNA and RNA molecules?
Although the base pairing between two strands of DNA in a DNA molecule can be thousands to millions of base pairs long, base pairing in an RNA molecule is limited to short stretches of nucleotides in the same molecule or between two RNA molecules.

What is the energy storage molecule produced by photosynthesis?
My guess would be ATP (short for Adenosine triphosphate) and NADPH
Will the monkees regroup?
Unlikely.The Monkees have got back together several times to go on tour.They are about to go on a short tour of England although Mike Nesmith is not joining them.

What is the main storage molecule in animals?
Animals have molecules that can store energy for short term and long term periods of time. Animals use carbohydrates as short term storage and Lipids as long term storage.
Why does H2 molecules exist when He2 does not?
H2 technically does contain molecules. Or at least, molecule. H2 is two hydrogens covalently bonded, so that the lowest energy level is filled. Since H2 has two atoms (hydrogen and hydrogen), it is not an element, because there is more than one atom. H2 is a molecule itself. However, in context of nature, it is rare that you would ever find an H2 molecule on its own unless you were working with one in a laboratory. So, if you were considering the whole of an H2 gas, there would be many molecules of H2. Short answer: H2 is a molecule itself. Many H2 means there are many molecules of H2.
