  1. Polyketones By Kathlene Robinson & Victoria MacDonald

  2. Structure Ethylene and carbon monoxide, along with a palladium (ıı) catalyst will produce a polyketone.

  3. Cons of Design & Structure • Palladium (ıı) is rare, and has to be mined. • In Canada, it is mined in Sudbury, Ontario.

  4. Pros of Design & Structure • Ethylene and carbon monoxide are extremely cheap. The chemistry involved in the reaction is very simple. • It is a crystalline structure, causing it to be very durable.

  5. Uses • Car Parts • Appliances • Electrical applications • Gears • Bearings • Tubing

  6. Strength • Carbonyls allow polyketones to be very strong crystals.

  7. Pros of Strength • Because there is a strong attraction between the molecules, there is a high melting point.

  8. Cons of Strength • Because of the tight bonds between the molecules and crystalline structures, polyketones are very brittle.

  9. Pros • When a methyl group is added onto the ethyl, it causes the structure to not bond together so tightly.

  10. Cons • When the methyl group, or propylene, is added to the polyketone the melting point drops.

  11. Environmental Impacts • Products made from polyketones, such as car parts and other thermoplastics are recyclable.
