The aminoalkoxysilanes, γ‐aminopropyltriethoxysilane and N‐aminoethyl‐γ‐ainopropyl‐trimethoxysilane, were chemically modified by ring‐opening addition of γ‐propanesultone. Surfaces coated with polymers from these new monomers have, at the surface, zwitterionic functions of sulfobetaines which are attached to the polymeric siloxane backbone. They showed good wettability, with critical surface tensions as high as 50 dynes/cm.
