EPOXY GROUP-CONTAINING POLYORGANOSILOXANE, CURABLE RESIN COMPOSITION CONTAINING EPOXY GROUP-CONTAINING POLYORGANOSILOXANE, AND CURED PRODUCT OF SAME

摘要

The present invention provides: an epoxy group-containing polyorganosiloxane which exhibits high compatibility with an initiator or other resins, while having low viscosity, high curing rate, excellent adhesiveness and excellent impact resistance; a curable resin composition; and a cured product. An epoxy group-containing polyorganosiloxane which comprises M unit (R¹R²R³SiO_1/2), D unit (R⁴R⁵O_2/2) and Q unit (SiO_4/2), wherein the content of T unit (R⁶SiO_3/2) relative to all silicon atoms is 80 mol% or less. The epoxy group contains a group represented by formula (2) and a group represented by formula (3).　In formula (2), R⁸ represents an optionally substituted divalent organic group having from 1 to 20 carbon atoms; and g represents 0 or 1.　In formula (3), R⁹ represents an optionally substituted divalent organic group having from 1 to 20 carbon atoms; and h represents 0 or 1, 0 ≤ i ≤ 8 and 0 ≤ j ≤ 8.
