| 摘要 |
The present invention relates to rodenticidal foams based on hydrophilic polymers, of the following composition: a) rodenticidal active compound, b) hydrophilic polymers having an average molecular weight of 2,000 to 60,000 (determined by means of gel permeation chromatography (GPC) from the series consisting of ling-chain polyurethanes, polyesters, polyester-polyols, polystyrenes, polybutadienes and maleic acid polymers, which are in each case modified in the polymer chain by carboxylic acid groups or amino groups, c) long-chain aliphatic C6-C22-fatty acids, such as palmitic acid, dodecanoic acid and stearic acid, or alkali metal, alkaline earth metal and ammonium salts thereof, d) and if appropriate further auxiliaries from the series consisting of dyestuffs, emulsifiers, solvents, perservatives, attractants and baits.
