Abstract
A polyorganosiloxane may be high in elasticity and/or strength. The polyorganosiloxane may include an M unit (RRRSiO) at a content of 10 mol. % or more relative to the total of silicon and a T unit (RSiO) at a content of 80 mol. % or less relative to the total of silicon. The polyorganosiloxane may have an alkoxy group bound, at a content of 0.07 to 4 wt. %, based on total polyorganosiloxane weight, and a reactive functional group bound to silicon, with 3 to 12 of the reactive functional groups bound on a number basis per a molecular weight of 1000 of the polyorganosiloxane. The weight loss of the polyorganosiloxane at 110° C. under 0.15 torr for 2 hours may be 5 wt. % or less.
