Abstract
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; especially wherein at least one of the radicals R, Ror Ris —CH—CH(CH)—S(O)—R, —CH—CH—CH—S(O)—R, —CH—CH(R)—CH—Ror —CH—CH═CH—R, Ris hydrogen or halogen, Ris a monovalent perfluorinated alkyl or alkenyl, linear or branched organic radical having four to twenty fully fluorinated carbon atoms; or —CHCH(CF)CF, 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.
