ER_Polymerization

== =CP Assignment= The diagrams below show a monomer for some of the six common plastic types. To make plastics, we take these monomers and "polymerize" them. That's an academic way of saying, we link them together in a chain that repeats many, many times.

As you learn about polymerization, you will also learn some Omnigraffle skills. We will do a lot of work in Omnigraffle this year. Here are the tasks you need to complete:
 * First, highlight all of the elements of the monomer, and "Group" them;
 * Second, copy the group, paste it, and move it so that it links with the first group;
 * Third, repeat the process until you get to the end of the page;
 * Finally, add three dots at each end to show that a real plastic molecule goes on and on...

=Honors Extension= Academic chemists have developed a short-hand notation for carbon=based molecules. Carbon-to-carbon connections are shown as zig-zag lines, with carbon at each vertex and end. Hydrogen atoms are typically omitted.


 * Go to wikipedia and find the article for one of the polymers listed below.
 * Drag a copy of the monomer's picture onto your desktop.
 * Crop it so that only the structural diagram remains.
 * Drag the cropped picture into this document, resize it, and duplicate it to show how it would polymerize.
 * Drag in one additional copy of the image, lock it down, and add a capital letter C everywhere the carbon atom appears in the diagram.

Some Polymer Choices:
 * Neoprene
 * Polystyrene
 * Polyacrylonitrile
 * Polyvinyl butyral
 * Polyvinyl alcohol
 * Polycarbonate
