ABSTRACT:
An improved method for the formation of naled-containing synthetic resin shaped bodies is disclosed. A mixture of a synthetic resin, naled, and a surface porosity control component is extruded in the presence of an acid-resistant material (e.g., nickel or nickel alloys or the like). Other insecticides (e.g., carbamates) may also be included in the naled-containing mixture, if desired. The resulting extrudates are useful as pet collars or the like and are formed without substantial degradation of the naled as has been found to occur in attempts to extrude in the presence of carbon steel.
