Abstract
Insecticides, and particularly termiticides, may be dissolved in monomers polymerized to form foamable polymers, such as polystyrene. The resulting monomer and insecticide may then be polymerized in a conventional manner and either impregnated with a blowing agent or expanded using an extrusion process to produce polymeric foam having insecticidal properties. The polymer may also contain a flame retardant. Such polymers and the foam made therefrom may be used in the construction industry, particularly where insect infestation is a concern.
