Abstract
Molten, water soluble polymer is used as a binder for agriculturally effective active ingredients in a water free encapsulation process. For finely divided solid active ingredients, a solvent for the binder can be used to increase the amount of bound active ingredient. For water insoluble active ingredients, the binder provides a method for rendering the active ingredient dispersable in water.
