The instant invention relates to a composition comprising a) an organic material which is susceptible to oxidative, thermal or light-induced degra- dation, 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 R2, R3 or R4 is is -CH2-CH(CH3)-S(O)p-R12, -CH2-CH2-CH2-S(O)p-R12, -CH2-CH(R11)-CH2-R12 or -CH2-CH=CH-R12, R11 is hydrogen or halogen, R12 is a monovalent perfluorinated alkyl or alkenyl, linear or branched organic radical having four to twenty fully fluorinated carbon atoms; or -CH2CH2(CF2)mCF3, 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 mat- erials, 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 moi- sture 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. |
