Two hybrid polymers, poly(methylsilsesquioxane)‐poly(2,2‐diethoxyethyl acrylate) and poly(methylsilsesquioxane)‐poly(1,3‐dioxolan‐2‐ylmethyl acrylate), were synthesized and used for preparation of stable surface coatings. Their acetal side groups could be functionalized via solution‐dipping with different primary amines and hydroxylamines after acidic deprotection and thus allowed for flexible modification of the surface hydrophilicity. Functionalization with a thermo‐responsive polymer resulted in a thermo‐responsive surface with temperature‐dependent contact angles. Further, the two types of acetals showed different stability toward acidic treatment and could be addressed independently.
