    摘要： The organopolysiloxane composition proposed is a blend of a conventional diorganopolysiloxane or a dimethylpolysiloxane oil and a limited amount of an (etherified) perfluoroalkyl group-containing organopolysiloxane such as those represented by the general formula ##STR1## in which Rf is a perfluoroalkyl group of 1 to 14 carbon atoms or an etherified perfluoroalkyl group of 2 to 14 carbon atoms having at least one oxygen atom between two carbon atoms forming an ether linkage, R is a hydrogen atom or a monovalent hydrocarbon group having 1 to 10 carbon atoms, Y is a divalent organic group having 2 to 5 carbon atoms, the subscripts a and b are, each independently from the other, zero or a positive integer and the subscripts c and d are, each independently from the other, zero, 1, 2 or 3 with the proviso that at least one of the subscripts a, c and d is not zero. By virtue of the admixture of this unique adjuvant, the silicone oil composition can be imparted with greatly increased spreadability even on the surface of a fluorocarbon resin film although the surface tension of the oil is not remarkably decreased thereby.

    摘要： A chain organopolysiloxane is obtained by polymerizing a fluorine-containing cyclotrisiloxane of the general formula: ##STR1## (wherein R.sup.1 is a monovalent hydrocarbon group, and Rf is a perfluoroalkyl group or perfluoroalkyl ether group)in the presence of a lithium silanolate catalyst, silylating the resulting polymerization product, and treating the silylated product at a temperature of not lower than 100.degree. C. under a reduced pressure of not higher than 10.sup.-1 mmHg to remove volatile components therefrom. The organopolysiloxane is essentially free of volatile low-molecular siloxanes. Therefore, the chain organopolysiloxane can be used without the problems which might arise from the volatile low-molecular siloxanes, such as evaporation of low-molecular siloxanes from a cured rubber product with the result of electrical-contact troubles.

    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.
