Beschreibung
Zusammenfassung:	Disclosed herein is an aqueous insecticidal composition characterized by an aqueous polymer fine particle dispersion containing at least one type of organic insecticidal active substance whose water solubility is not more than 5 g/l at 25 °C/1013 mbar and having a mean particle size, determined by dynamic light scattering, of not more than 500 nm, wherein the polymer particles containing at least one insecticidal active substance exhibits a positive surface charge and the aqueous dispersion of active substance containing polymer particles is obtained by radical aqueous emulsion polymerisation of an ethylenically unsaturated monomer composition M, in which said ethelenycally unsaturated monomer M contains at least one type of insecticidal active substance in a dissolved form. Also disclosed is the use of the aqueous insecticidal composition for protecting lignocellulose-containing materials, in particular wood, against attack by harmful insects.
