    摘要: An improvement is proposed in a frame-supported pellicle, i.e. a thin transparent film of a polymeric resin adhesively bonded to a frame member, used for dust-proof protection of a photomask in a photolithographic patterning work for the manufacture of electronic devices. The improvement comprises using, as the adhesive, an organopolysiloxane-based composition which comprises (a) a perfluoroalkyl-containing diorganopolysiloxane having at least two vinyl groups per molecule, (b) an organohydrogenpolysiloxane having at least one epoxy group and (c) a platinum catalyst for promoting the hydrosilation reaction between (a) and (b). As compared with conventional adhesives, a quite good adhesive bonding strength can be obtained with this adhesive even when the membrane is made from a fluorocarbon group-containing polymeric resin and the adhesive layer obtained therefrom is highly resistant against ultraviolet irradiation to ensure a long serviceable life of the pellicle.

    摘要: A fluorine-containing curable composition comprises (A) a linear perfluoro compound having at least two secondary amino groups per molecule and a divalent perfluoroalkylene or divalent perfluoropolyether structure in the main chain, and (B) a crosslinkable fluorinated compound having at least three functional groups which are crosslinkable with the secondary amino groups of (A). This composition readily cures, with standing at room temperature or heating only, to a cured product having excellent solvent and chemical resistance.

    摘要: A straight-chain organopolysiloxane represented by the general formula: ##STR1## wherein R.sup.1 represents a monovalent hydrocarbon group, R.sup.2 represents a bivalent organic group, Rf represents a perfluoroalkyl ether group or a perfluoroalkyl group, X represents a hydrogen atom or an organosilyl group, and n is an integer of 15 to 4,000 and having a content of cyclic polysiloxanes with a molecular weight of 3,000 or below of 50 ppm or below. This organopolysiloxane is novel in that the content of cyclic siloxanes with a molecular weight of 3,000 or below is only 50 ppm or below and the organopolysiloxane can obviate contact failure due to volatilization of components or surrounding contamination due to bleeding when used as materials in the field of electricity and electronics or as building materials.
