摘要：Aqueous, storage-stable emulsion (A) of one or more silylated polymers (I), haspH 2-11 and solids content 40-95wt.%, and includes at least one anionic and/or nonionicemulsifier able to produce an oil-in-water emulsion. The emulsion is formed by addingthe aqueous emulsion components to a mixture of emulsifier(s) and polymer(s) (I).Aqueous, storage-stable emulsion (A) of one or more silylated polymers (I), has pH 2-11and solids content 40-95wt.%, and includes at least one anionic and/or nonionic emulsifierable to produce an oil-in-water emulsion. The emulsion is formed by adding the aqueousemulsion components to a mixture of emulsifier(s) and polymer(s) (I); and where R 7> =group that imparts self-emulsifying properties, at least part of the emulsifier(s) can bereplaced by (I).
