STABLE CONCENTRATE FORMULATIONS AND EMULSIONS OF WATER-INSOLUABLE ORGANIC PESTICIDES, THEIR USE AND PREPARATION

摘要

Stable emulsion formulations of water-insoluble organic pesticides are prepared by commingling the pesticide with an aqueous dispersion of a graft copolymer comprised of a reactive polymeric surfactant (RPS) base polymer and a nonionic hydrophobic grafted composition whereby the surfactant on the surface is bound thereto by the graft chains to a particle which is an aggregate of the RPS graft and pesticide. The resulting product is more stable to coalescence than emulsions made with conventional or polymeric surfactants.
