The following are claimed: (A) rodenticidal soft foams comprising: (a) rodenticidal active agent; (b) hydrophilic polymers with an ave. mol. wt. of 2,000-60,000 (measured by gel permeation chromatography), selected from long chain polyurethanes, polyesters, polyester-polyols, polystyrenes, polybutadienes and maleic acid polymers (each of which are modified in the polymer chain by carboxylic acid and amino gps.); (c) long-chain aliphatic 6-22C fatty acids; and opt. (d) other auxiliaries selected from dyes, emulsifiers, solvents, preservatives and baits. (B) premixt. for preparing rodenticidal soft foams comprising components (a)-(d) as described above. |
