Damage to force and message devices j from rodents has been a problem for many years. In general

there are two ways to solve this problem. The first] and best way would be the complete elimination of rats and j mice through the use of traps, questioner poisons and]

rodent-proof constructions. However, these are procedures

largely impossible because the rodents are in remote undeveloped

populated areas where communication cables are laid, ''

j difficult to catch or poison 3ind. This program \ is therefore impractical as well, as would be the cost for the open position of traps and the distribution of poisons over long distances too great.

The second method is to provide reel repellant compositions in a coating which can remain on communication cables without deteriorating their appearance or behavior, but with the effect that the rodents will not attack the cables or the cables Items to be protected make these compositions should not damage cardboard, fabrics or other materials that may be chemically interrelated. The repellent material must be sufficiently stable * to ensure continued effectiveness under a wide variety of conditions of handling, transport and storage; object to be protected '·. not excessively increases _o

An object of the present invention is to provide one Rejection for rodents, in which the active Component to maintain their rodent repellent activity receives, in spite of the fact that its volatility is such, that it would normally go away in a short time " Another goal is to create a rejection composition for rodents, which has improved stickiness on substrates such as polyethylene.

The invention now relates to a repellent composition for animals which is characterized in that it consists of an organic film-forming material and a tributyltin _{compound uniformly distributed therein which has the formula (C 4} Hg) ₅ SnQ, wherein Q is chloride, fluoride, oxide and Can mean acetate. The composition range is as follows

The new erfindungegemäßen compositions have the advantage that they _t adhere well to a polyethylene insulation are 3tabil at high temperatures and against rodents are highly resistant "It has been unexpectedly found that in the new erfindungsgeinäßen compositions of the vapor pressure of the active triorganotin compound was suppressed _F which the time for the compositions to retain their repellent properties has been greatly increased.

"The preferred composition of the invention is as follows:

The invention is explained in more detail by the following examples,

A stainless steel reaction vessel was charged with -34.81 parts of chlorinated rubber gumini ("Parlon S-20" manufactured by "Hercules Powder Co,., Wilmington, Delaware) and 23.46 parts by weight of toluene. The mixture was heated with stirring to a temperature of 66 ° C. While the mixture was kept axif 66 ^J 0 _s , 25 * 88 parts by weight of chlorinated biphenyl were added (17.35 parts by weight of the product Arochlor 1254 and 8 »53 parts by weight, ~ Portions of product Arochlor- 5460, both sold by Monsanto Chemical Co-, 8t Louis, Missouri) -.,

The reaction mixture was stirred, longer observed until no undissolved solids. "The clear homogeneous solution was cooled to 33 ⁰ C followed by 15/85 weight _f" parts by tributyltin chloride wurden- added with stirring. The product exhibited a viscosity of 9850 centipoise (Z-5 avf on the Gardner scale).

The new compositions of the invention can be applied directly to a polyethylene cable without laborious surface preparation. Good adhesion was obtained by cleaning with a solvent to remove oil and physical contamination. The film had a sufficiently high tensile strength that shrink wrapping was possible, which indicated maximum capillary adhesion to polyethylene _o This also gives a film that shrinks and dries when the wire is pressurized. This gives a tough, tightly adhering coating _f

From the following table it can be seen that the coated Cable with a double strand of wire does not have such great flexibility, especially after aging at elevated temperatures, as a cable with a strand of wire. The mechanism the double strand prevents the movement of the cable,
