    • 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 R2, R3 or R4 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 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.
    • 本发明涉及一种组合物,其包含a)对氧化,热或光诱导降解敏感的有机材料,和b)至少一种式(I)化合物,其中一般符号如权利要求1所定义; 特别是其中基团R 2,R 3或R 4中的至少一个为-CH 2 -CH(CH 3)-S(O)p -R 12,-CH 2 -CH 2 -CH 2 -S(O)p -R 12,-CH 2 -CH( R11)-CH2-R12或-CH2-CH-CH-R12,R11是氢或卤素,R12是具有四至二十个完全氟化的碳原子的一价全氟化烷基或烯基,直链或支链有机基团; 或-CH 2 CH 2(CF 2)m CF 3,m为3至12,p为0,1或2.式I化合物可用作有机材料例如合成聚合物的表面能的还原剂。 具有这种表面能降低的聚合物具有“易清洁”,“自清洁”“防污”,“释放”“防刮涂”,“耐油性”,“耐溶剂性”,“耐化学性” “自润滑”,“耐划伤性”,“低吸湿性”,“抗污性”,“滑爽性”和“疏水性表面”; 和抗蛋白质和抗微生物(例如细菌,真菌和藻类)的抗粘附性。
