More Information
Summary:The invention relates to the combination of an agrochemical active substance, especially herbicides from the group of the sulfonyl ureas, with a polymer while forming hydrogen bridges for the controlled release of said active substance. The polymer and the active substance have functional groups that facilitate the formation of hydrogen bridges. The preferred polymers are polyvinyl alcohols or partially saponified polyvinyl acetates. La invencion describe una combinacion de una sustancia agroquimicamente activa, especialmente herbicidas del grupo de las sulfonilureas, con un polimero mientras se forman enlaces de hidrogeno para la liberacion controlada de la sustancia activa; el polimero y la sustancia activa tienen grupos funcionales que facilitan la formacion de enlaces de hidrogeno; los polimeros preferidos son los alcoholes de polivinilo o los acetatos de polivinilo parcialmente saponificados.
