Zusammenfassung: | PURPOSE: To obtain shaped articles, e.g. pet collars, capable of properly and persistently releasing an active compound of an animal insecticide, etc., for a long period and processing the articles by a conventional method as a thermoplastic material and useful for extermination of insect pests. CONSTITUTION: The shaped articles comprises (A) a thermoplastic elastomer comprising a copolyester, e.g. a copolyester composed of many repeated short-chain ester units and long chain ester units linked by an ester bond and containing about 15-65wt.% short-chain ester unit represented by formula I (R is bifunctional group of a dicarboxylic acid having a molecular weight smaller than about 350; D is a bifunctional group of an organic diol having a molecular weight smaller than about 250) and about 5-80wt.% long-chain ester unit represented by formula II (G is a bifunctional group of long-chain glycol having about 350-60,000 average molecular weight) and (B) an active compound containing a conventional additive, preferably insecticide for animals, especially preferably a parasiticide. The shaped articles can be processed as a thermoplastic material. |
