Abstract
An improved method is provided for preparing an insect-active assembly which can provide insect repellency, insecticidal action, or both and which is adapted to be directly affixed to the garment worn by a person. The assembly is comprised of a polymeric body which contains an insect-active composition, as a volatile plasticizer, which, over time, migrates from the polymeric body to provide the desired degree of insect-active action. The improvement consists of preparing the assembly at low temperatures thus preventing losses of the insect-active component to the environment, during processing under conditions employed in the prior art. A key element of this improved process is the use of a thermoplastic latex in place of thermoplastic resins or polymers used in earlier versions of assembly preparation. The thermoplastic latices, which have been plasticized with the insect-active composition, can readily be dried at low temperatures, to form the assembly.
