(Evolving emission legislation in both the USA and Europe is requiring the automotive industry to develop novel solutions for their fuel/vapour circuits, yielding significant improvements in evaporative emission behaviour. Thus material structures with excellent barrier properties against various automotive gasoline fuels are receiving a significant amount of attention for this purpose. CARILON Polymer, an aliphatic polyketone (PK) from SHELL Chemicals holds promise as such a barrier construction material)
found: EXPRESS polymer letters, June 2008:pp. 440-441 (Polyketones are a class of high performance materials that have attracted a great deal of attention due to their high thermal stability, which is a result of the incorporation of thermally stable carbonyl and/or aromatic groups in the polymer backbones. These polymers typically exhibit high glass transition temperatures and high melting points, which makes them ideal candidates for use as stationary phase in chromatography applications. Aromatic polyketones are synthesized by Friedel-Crafts or nucleophilic aromatic substitution reactions. The materials are usually insoluble and intractable. Aliphatic polyketones have been prepared through the copolymerization of carbon monoxide with ethylene or [alpha]-olefins)
found: Polymer journal, June 2016:p. 673 (Aromatic polyketones, bearing the main chain consisting of arylene and carbonyl groups, have received much attention because of their potential applications as superengineering plastics. However, the range of accessible aromatic polyketones has been limited, and all the methods rely on step-growth condensation polymerization, rather than chain-growth polymerization. Thus we focused on the transition-metal-catalyzed alternating copolymerization of alkenes and carbon monoxide, which produces aliphatic polyketones bearing saturated aliphatic main chains)
