Abstract
Provided are: a novel organopolysiloxane compound containing a vinylene group, which can be used as a base polymer for an addition-curable silicone composition, particularly an organopolysiloxane compound containing a terminal vinylene group; and a method for producing the organopolysiloxane compound. An organopolysiloxane compound characterized by having at least one unit represented by formula (1) as a partial structure, and also characterized by being linear or branched. [R's independently represent a hydrogen atom or a monovalent hydrocarbon group having 1 to 20 carbon atoms; R's independently represent a hydrogen atom, a monovalent hydrocarbon group having 1 to 20 carbon atoms, or a group represented by formula (a); x represents an integer of 0 to 1,998; R's independently represent a group represented by formula (a); R's independently represent a monovalent hydrocarbon group having 1 to 20 carbon atoms; a represents an integer of 1 to 2,000; and b represents an integer of 0 to 1,999.]
