<p>A method for preparing an organopolysiloxane compound by mixing (A) an organopolysiloxane of the formula (1):
wherein R 1 is a monovalent hydrocarbon group and may be the same or different, R is a divalent hydrocarbon group, and n is an integer of at least 2, with (B) an organic compound of the formula (2) or (3):
wherein R 2 is H or a monovalent hydrocarbon and R 3 is a divalent hydrocarbon and (C) an organic compound of the formula (4):
wherein R 1 and R 3 , respectively, have the same meanings as defined above, R 4 is a monovalent hydrocarbon group, and p is 0 or 1, wherein components (A), (B) and (C) are reacted with one another under conditions that a ratio between an amino group equivalent P NH in component (A) and an isocyanate group equivalent P NCO in components (B) and (C) is such that 0.8 ‰¤ (P NCO / P NH ) and a molar ratio between component (B) and component (C) is such that 0.6 ‰¤ [component (B)/component (C)].</p> |
