    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.
