Polymerization Lab Report 2

Macromolecules can also be formed from cyclic monomers such as cyclic hydrocarbons, ethers, esters, amides, siloxanes, and sulfur (eight-membered ring). Thus, ring-opening polymerization is of particular interest, since macromolecules of almost any chemical structure can be prepared. Choose two of the above type polymers to explain the mechanism and chemical reaction of polymerization process.

Note: I need a simple explanation for this lesson for my presentation. Thank you!

Write or introduce the following topics of polymer : • Thermoplastic/thermoset elastomer •Addition/condensation • Step/chain polymerization • How chains interact -> strength and consequences of crosslinking • Molecular average vs number average -> polydispersity

This polymer is composed of 2 monomer units: an acid chloride and an amine. In the box below, draw the structure of both monomers. (8-10 C (CH₂)6-C CH₂ 어 H n • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • Do not include lone pairs in your answer. They will not be considered in the grading. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. • Separate structures with + signs from the drop-down menu.
