Abstract:
1. A method for preparing an organopolysiloxane compound, which comprising mixing (A) an organopolysiloxane of the following formula (1): wherein R 1 is an unsubstituted or substituted monovalent hydrocarbon group having 1 to 10 carbon atoms and may be the same or different, R is a divalent hydrocarbon group having 1 to 10 carbon atoms, and n is an integer of at least 2, with (B) an organic compound of the following general formula (2) or (3): wherein R 2 is a hydrogen atom or an unsubstituted or substituted monovalent hydrocarbon group having 1 to 3 carbon atoms, and R 3 is an unsubstituted or substituted divalent hydrocarbon group having 1 to 20 carbon atoms, wherein R 2 and R 3 , respectively, have the same meanings as defined above, and (C) an organic compound of the following general formula (4): wherein R 1 and R 3 , respectively, have the same meanings as defined above, R 4 is an unsubstituted or substituted monovalent hydrocarbon group having 1 to 3 carbon atoms, and p is 0 or 1, thereby preparing an organopolysiloxane compound, 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)].
