CARILON Polymers, a.k.a. aliphatic polyketones, can be used in a wide variety of applications. For example automotive and industrial, oil and gas, consumer goods, and medical materials all use aliphatic polyketones. This wide range of applications is due to these particular polymers unique attributes such as chemical resistance, strength, low permeability to hydrocarbons, and performance over a broad temperature range.
Shell Company has found that gas phase processing works to produce these polyketones. This process was initially used for the production of polyolefins. The polyketones produced in this process have very different properties from polyamides and polyacetals. Aliphatic polyketones are produced in bulk quantities but have recently for reasons of divestment Royal Dutch/Shell companies are stopping the production of CARILON polymers.Pertinent Text References
Question 1: What unique combination of physical properties does the CARILON polymer have that materials traditionally used, such as polyamides and polyacetals, lack?
Question 2: Draw a general structure for a polyketone.
Question 3: What is a polyolefin? (Textbook)
Question 4: There are several important implications of this new technology. Give an example of how this new plastic can impact society.
"In December 1998 Shell announced that CARILON was one of several businesses to be divested. In 1999 the business was thoroughly marketed and discussions were held with several interested parties, however none of these discussions developed into a sale."

Why do you think that, despite all of the good things said about this new polymer technology, that not a single business decided to purchase the CARILON Company from Shell?
