Abstract
PURPOSE: To prepare a borosiloxane polymer having improved resistance to hydrolysis, in considerably improved yield, by the thermal polycondensation of a borodiphenylsiloxane compound.
CONSTITUTION: A borodiphenylsiloxane polymer having ratios of IR absorption peaks of 0.70W1.20 (δ1340/δ695), and 0.6W1.2(δ1080/δ695), is prepared by heating and polymerizing a borodiphenylsiloxane compound of formula (n is 1,2) in the presence or absence of solvent at 140W400°C. The compound of formula is prepared by reacting boric acid with diphenylsilanediol at 80W140°C.
USE: Hardener of epoxy resin, additive for synthetic fiber, raw material of ceramics, sintering assistant of ceramics, adhesive, raw material of lens, etc.
