Abstract

VOC or compressed gas containment devices, such as polymer fuel tanks, are made from a polyoxymethylene polymer composition. The polymer composition contains a polyoxymethylene polymer that is directly or indirectly chemically attached to an impact modifier. In one embodiment, for instance, a coupling agent bonds the impact modifier to the polyoxymethylene polymer. In order to preserve the permeability of the polymer material when combined with the impact modifier, a polyoxymethylene polymer is used that contains a low level of low molecular weight constituents.
