Abstract:
1. A composition comprising at least one insecticide, a nonionic and/or ionic dispersant, and a grafted aqueous polymer dispersion, wherein the insecticide is transfluthrin, wherein the polymer dispersion is prepared by radical-initiated emulsion copolymerization in the presence of a hydrocolloid comprising starch as a grafting base, of a monomer mixture comprising a) 30 to 60% by weight, based on the monomer mixture weight, of at least one styrene or substituted styrene, (b) 60 to 30% by weight, based on the monomer mixture weight, of at least one C1-C4-alkyl(meth)acrylate, and (c) 0 to 10% by weight, based on the monomer mixture weight, of other ethylenically unsaturated copolymerizable monomers, and wherein the starch (d) employed is 10 to 40% by weight of degraded starch with a molar weight M n =500 to 10 000, the total of (a)+(b)+(c)+(d) being 100%, and the radical-initiator employed for the radical-initiated emulsion polymerization is a graft-active, water-soluble redox system, and wherein the polymer dispersion after drying has a glass transition temperature of 40° C. to 80° C.
