- NOVEL ETHYNYL-GROUP-CONTAINING ORGANOPOLYSILOXANE COMPOUND METHOD FOR PRODUCING STRAIGHT-CHAIN ORGANOPOLYSILOXANE COMPOUND CONTAINING ETHYNYL GROUP AT BOTH MOLECULAR CHAIN ENDS METHOD FOR PRODUCING ALKOXYSILYL-ETHYNYL-GROUP-TERMINATED ORGANOSILOXANE POLYMER ROOM-TEMPERATURE-CURABLE COMPOSITION AND MOLDED ARTICLE THAT IS CURED PRODUCT OF SAME

摘要

The present invention is an organopolysiloxane compound, which has at least one of the following formula (1) units as a partial structure, and is either linear or pulverized. Accordingly, there is provided a novel ethynyl group-containing polyorganosiloxane compound, and a method for preparing a straight chain organopolysiloxane compound containing a molecular chain sock end ethynyl group which can easily adjust the degree of polymerization and is excellent in productivity.
