ORGANOPOLYSILOXANE, METHOD FOR PRODUCING SAME, AND CURABLE SILICONE COMPOSITION

摘要

The present invention is a novel organopolysiloxane having a silicon-atom-bonded hydrogen atom at both ends of the molecular chain, and is represented by the general formula: HR1 2SiOSiR1 2-R3-R1 2SiO(R2 2SiO)mSiR1 2-R2-R1 2SiOSiR1 2H. (In the formula, R1 and R2 each independently represent a C1-12 alkyl group, a C6-20 aryl group, or a C7-20 aralkyl group, wherein at least 10 mol% of all R2s is said aryl group; R3s each independently represent a C2-6 alkylene group; and m is an integer of 5 or greater.)
