The instant invention relates to a composition comprising a) an organic material which is susceptible to oxidative, thermal or light-induced degradation, and b) at least one compound of the formula (I) wherein the general symbols are as defined in claim 1 ; especially wherein at least one of the radicals R 2 , R 3 or R 4 is —CH 2 —CH(CH 3 )—S(O) p —R 12 , —CH 2 —CH 2 —CH 2 —S(O) p —R 12 , —CH 2 —CH(R 11 )—CH 2 —R 12 or —CH 2 —CH═CH—R 12 , R 11 is hydrogen or halogen, R 12 is a monovalent perfluorinated alkyl or alkenyl, linear or branched organic radical having four to twenty fully fluorinated carbon atoms; or —CH 2 CH 2 (CF 2 ) m CF 3 , 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. |
