A pH-sensitive polymeric composition is used as a binder for other materials, such as webs of non-woven water-dispersible fibers, to produce products which are completely disposable at selected non-neutral pH's. The polymeric composition, which has film-forming characteristics and water-barrier properties at substantially neutral pH's and yet is solubilizable and thus disposable at substantially non-neutral pH's, comprises a silane crosslinked interpolymer of an alkyl acrylate and a monomer interpolymerizable therewith such as, in the preferred alkaline labile embodiment, acrylic acid. The silane crosslinking monomer is preferably 3-(trimethoxysilyl)-propyl methacrylate or 3-(trimethoxysilyl)-propyl acrylate.
