The invention relates to novel water-soluble or water-dispersible polyurethane compounds and to compositions that contain the novel compounds and are useful, for instance, as low adhesion backsize for adhesive tapes. The invention also relates to processes for preparing the novel compounds, compositions and tapes. The novel polyurethane compound is a water-soluble or water-dispersible polyurethane polymer whose polymer chain includes segments derived from a silicone polycarbinol and whose polymer chain is endcapped with a silane. The process is a process for preparing a water-souble or water-dispersible polyurethane polymer which process comprises: (a) preparing an isocyanate-terminated urethane prepolymer by reacting together a polyisocyanate, a polyester polyol or a polyether polyol, a low molecular weight diol chain extender and a silicone polycarbinol, and (b) reacting the isocyanate-terminated urethane prepolymer with a low molecular weight diamine chain extender and a monoamine silane chain terminating agent.
