Aliphatic polyketones are a family of polymers prepared by the polymerisation of olefins and carbon monoxide in a perfectly alternating sequence. BP Chemicals produces these materials using a proprietary palladium catalyst in a continuous polymerisation process.
They are crystalline thermoplastics which offer a unique combination of mechanical, high temperature, chemical resistance, wear and barrier properties. The resistance to permeation of polyketones specifically to oxygen, hydrocarbons and other reagents is comparable to that of ethylene vinyl alcohol copolymers (EVOH). This performance creates the potential for use in pipe applications for industrial chemicals, solvents, fuel and automotive products.
