    Abstract: Fluoroelastomer compositions comprising fluoroelastomers having copolymerized units of a nitrile-containing cure site monomer are cured with certain hydrazide curatives. The hydrazide is of the general formula R1(C(O))nNHNHR2, wherein n is 1 or 2; R1 is NH2, NHNH2, NHR3, NR32, NHNHC(O)NH2, NHNHC(O)NHNH2, NHNHR2, or NHC(O)NHNH2; R2 is H, alkyl, aryl, heterocycle, CO2R3, C(O)R3, CH2R4, or C(O)R4; R3 is alkyl, aryl, heterocycle, or CH2R4; and R4 is a fluoroalkyl group.

    Abstract: Provided are liquid perfluoro-n-alkanes that are highly transparent to UV wavelengths ranging from about 150 nm to 165 nm, and to the method by which high transparency may be obtained. The liquid, perfluoro-n-alkanes are useful in optical couplants, optical cements, optical elements, optical inspection media for semiconductor wafers and devices, and immersion photolithography at 157 nm exposure wavelength.

    Abstract: A new class of low temperature initiators has been found, enabling fluoroolefin polymerizations at relatively low temperatures. These initiators are diacyl peroxides which allow improved productivity and product properties, as well as more favorable reaction conditions.

    Abstract translation: 已经发现了一类新的低温引发剂,使氟烯烃在较低温度下聚合。 这些引发剂是二酰基过氧化物,其允许改进的生产率和产物性质以及更有利的反应条件。
