Polymers

Polymers Large chain like molecules that are built from small molecules called monomers. Many important biomolecules are also natural polymers. (know these!) –Protein (made up of amino acids) –DNA (made up of nuclei acids) –Starch (made up of sugar subunits) –cotton, silk and cellulose.

Polyethylene The simplest and best known synthetic polymer is polyethylene. Ethylene polyethylene (Monomer)(polymer) (Monomer)(polymer)

The properties of a polymer can be varied by substituting other elements or groups of elements for the hydrogens on ethyelene. Example - tetrafluoroethylene has fluorine atoms instead of Hydrogen atoms and is used to make Teflon which is used in nonstick coatings for cooking utensils

Polymers have different properties based on the side chain attachments, because these side chains will have different strengths of intermolecular attractions depending on their polarity. The between these long molecules determines the polymers flexibility, hardness or softness and melting temperature. The attractions between these long molecules determines the polymers flexibility, hardness or softness and melting temperature.
