A FUEL TANK AND A PROCESS FOR PRODUCING THE FUEL TANK

摘要

A fuel tank which is obtainable by a process comprising injection moulding a polymer composition containing a linear alternating copolymer of carbon monoxide and an olefinically unsaturated compound into one or more parts of the tank and joining the parts of the tank together, in which process the copolymer consists of repeating units of the formula -CO-(CH2-CH2-)- and repeating units of the general formula -CO-(G)-, where G is a moiety originating from an olefinically unsaturated compound of at least 3 carbon atoms and the molar ratio of -CO-(G)- to -CO-(CH2-CH2-)- is between 0.02 and 0.15, and the copolymer has a limiting viscosity number, measured in m-cresol at 60 DEG C, of between 1.4 and 2.0 dl/g; and said process.
