**Abstract**
 Carbon black filled polybutyl methacrylate composites for use as organic vapour sensors were fabricated by polymerisation filling. It was found that the composites have a wide synthesis window, giving composite materials with high gas sensitivity under different conditions. In comparison with composites made by solution mixing, these composites made by polymerisation filling were shown to have a much higher responsivity to organic vapours because of the superior distribution of the filler particles. The addition of a third component, vapour-grown carbon fibres and the post-treatment of the composites by gamma-irradiation is claimed to have proven effective in enhancing response stability. This paper focuses on the effects of synthesis conditions such as reaction time, reaction temperature and initiator content, on the number-average molecular weight of the resultant polymer matrix, and the electrical responsivity of the resultant composites against organic vapours. Also evaluated, were the inclusion of the vapour-grown carbon fibres and the irradiation treatment. 20 refs.
