ABSTRACT:
Polymeric microparticles having bound therewith a pesticide are disclosed. The microparticles are prepared by polymerizing a mixture of ethylenically unsaturated monomers. Active substances may be bound to the microparticles by introducing an ethylenically unsaturated function to the active substance and copolymerizing the resulting compound with the monomer mixture, or by polymerizing the monomer mixture in the presence of the active substance, or by impregnating the microparticles with a solution of the active substance.
