, m is 3 to 12, and p is 0, 1 or 2. The compounds of the formula I are useful as reducers of surface energy for organic materials, for example synthetic polymer. Polymers with such a reduced surface energy possess an “easy-to-clean”, “self-cleaning” “antisoiling”, “soil-release” “antigraffiti”, “oil resistance”, “solvent resistance”, “chemical resistance”, “self lubricating”, “scratch resistance”, “low moisture absorption”, “dirt pickup resistance”, “slip properties” and “hydrophobic surface”; and anti-adhesion properties against proteins and against microorganism such as for example bacteria, fungi and algae.
