Zusammenfassung: | What are disclosed are a method for making an emulsion polymer by polymerizing water insoluble free-radically polymerizable monomers, or monomer mixtures predominantly comprising such monomers, by emulsion polymerization in the presence of a polymerization initiator which is soluble in organic solvents and has at least limited solubility in water, and in the further presence of a free non-polymerizable emulsifying acid, also soluble in organic solvents, and the conversion of such an emulsion polymer by spray drying into a polymer powder which is completely soluble in organic solvents to form clear solutions from which polymer films of reduced water sensitivity can be formed. |
