4,' r; The present invention relates to new shaped articles which contain active compounds and are based on elastomeric styrene/butylene block copolymers which can be processed as thermoplastics, their production and their use for control of pests, in particular in stock and domestic animals.
Shaped articles which comprise active compounds for controlling pests are known. They are based on the slow release of active compounds from a carrier matrix of plastics which contains active compounds (compare, for example, Aries et al US P 3 814 061, Greenberg US-P 3 918 407, Miller et al US-P 3 944 662, Millionis et al US-P 4 041 151, Pasarela US-P 4 145 409, Greenberg and Cloud US-P 4 158 051, v. Bittera et al US-P 4 225 578. McDaniel et al EP-OS 0 052 411, Grubb et al US-P 3 852 416 and Pearce US-P 4 536 388).
C'
t C Ir I (rr( 20 4.4

4 250 The carrier employed practically almost exclusively for known shaped articles is PVC. Although other carriers are mentioned in the literature, as yet they have not found acceptance in practice. Thus, US-P 4 195 075 mentions, inter alia, that thermoplastic elastomers are also possible as carrier polymers for ear marks. However, this citation also describes exclusively examples using plasticiser-containing PVC as the carrier polymer.
This is also not surprising. PVC is inexpensive and ji *4G*54 I 4 4. C 1 14 4 4 444*. C
I
Le A 28 735 1 readily accessible. It is also miscible with other substances, in particular plasticisers, within wide limits. These plasticisers in PVC bodies containing active compounds have the function of keeping the active compound dissolved in the carrier and of transporting it slowly to the surface of the body. At the surface, the active compound evaporates or is rubbed off from the surface, together with the plasticiser. The interaction of the three components PVC carrier, plasticiser and active compound determines whether and to what extent the shape% article can be employed in practice.
If one component of the overall system is changed, it can no longer be predicted whether the system still acts in practice. This applies in particular if the plasticiser, which indeed has a key function in transportation of the active compound, is changed or omitted.
For various reasons, it is desirable to replace PVC as the carrier material. It is also advantageous to dispense partly or completely with the use of plasticisers. It was therefore a matter of discovering an active compound/ shaped article system in which PVC, as the carrier material, and plasticiser can be dispensed with and which nevertheless has a good action in practice.
Thermoplastic elastomers are materials which comprise elastomeric phases either mixed physically or bonded S chemically in polymers which can be processed as S thermoplastics. A distinction is made between polyblends, 4 6 A1 LeA 28 735 2in which the elastomeric phases are present in physically mixed-in form, and block polymers, in which the elastomeric phases are a constituent of the polymeric matrix.
Hard and soft regions are present side by side as a result of the build-up of the thermoplastic elastomers.
The hard regions form a crystalline network structure or a continuous phase, the interstices of which are filled by elastomeric segments. On the basis of this build-up, these materials have rubber-like properties.
A distinction may be made between 5 main groups of thermoplastic elastomers: 1.
2.
3.
4.
Copolyesters Polyether block amides (PEBA) Thermoplastic polyurethanes (TPU) Thermoplastic polyolefins (TPO) Styrene block copolymers t I *r 2 *t 20 t These 5 main groups show similar macroscopic physical properties, coupled with a completely different chemical build-up. In spite of these macroscopically similar properties, these main groups behave completely differently in respect of mixing in and release of active compounds.
The use of thermoplastic elastomers based on copolymers as carriers for active compounds is known. The use of styrene/butadiene block copolymers as carriers is described in EP-OS (European Published Specification) 338 821.

The present invention relates to 1. Shaped articles which contain active compounds, characterised in that they comprise, as carriers, thermoplastic elastomers based on styrene/butylene block copolymers, as well as customary additives if appropriate.
If 10 2. Processes for the production of shaped articles containing active compounds, characterised in that thermoplastic elastomers based on styrene/butylene block copolymers are mixed with active compounds and if appropriate custova.ry additives, and the mixture is processed in the customary manner.
It was surprising that active compounds also arrive at the polymer surface from the polymer matrix from thermoplastic elastomers based on styrene and butylene Swithout addition of plasticisers, since this capacity is limited to only a very few polymers. If only one component of the overall system is changed, the effects are unpredictable. Thermoplastic elastomers based on thermoplastic olefins (TPO) or thermoplastic polyurethanes, for example, are not capable of allowing active compounds ".25 to migrate to the surface.
o Qi4 e *C I' Le A 28 735 4 i I i The styrene/butylene block copolymers which can be used according to the invention consist of a polyethylenebutylene rubber central block with a polystyrene end block linked chemically to both ends. The polystyrene content is less than 30%. The polystyrene end blocks are distributed uniformly in the ethylene rubber matrix as spherical polystyrene domains.
Processes for the synthesis of suitable styrene block copolymer; are known, for example, from US-P 3 485 787, 4 006 116 and 4 039 629.
Suitable styrene/butylene block copolymers are obtainable, for example, under the commercial names ®Kraton G and ®Elexar from Shell Chemie GmbH and ®Thermolast-K- Compounds from Kraiburg.
