Types of Polymers

A chain of repeating units (called monomers)

• monomer

• dimer

• replicate

• polymer

Once formed, it can be heated and reformed over and over again

• thermoset

• thermoplastic

• elastomer

• kevlar

When water is added to instant snow polymer powder, what properties did we see happen with them?

• absorbs water and turns into a gel

• It's hydrophobic (afraid of water)

• absorbs water and expands

• material can be used to prevent fires

• puffed up like a slushy or icee
