Abstract: A water soluble rodent repellent composition which can be coated onto a material, e.g., a cable, which is laid into the ground. Ground moisture dissolves the composition, forming in the earth surrounding the cable a rodent repellent barrier thus preventing contact of the rodent with the cable or material. Any rodent repellent in a water soluble or water dispersible composition can be used. Specifically mentioned in the disclosure as now preferred effective rodent repellents are N,N-dialkyl sulfenyl dithiocarbamates, e.g., the N,N-dimethylsulfenyl dithiocarbamates, N,N-dimethyl-S-methylsulfenyl dithiocarbamate and N,N-dimethyl-S-tert-butylsulfenyl dithiocarbamate. The repellent is combined with dimethylsulfoxide and polyvinylalcohol or it is combined with one of dimethylsulfoxide and dimethylformamide, and with a hydroxyalkyl cellulose, e.g., hydroxypropylmethyl cellulose.

Abstract: A plastic composition especially suitable for use in barrel electroplating processes is prepared by incorporating in the plastic a siliceous filler and a heavy filler such as barium sulfate or zinc oxide in amounts such that the density of the molded composition is greater than the density of the plating bath.
