Abstract:
1. A method of producing an organopolysiloxane compound, the method comprising: (a) subjecting a cyclic imino ether compound represented by formula (I): wherein R to ring opening polymerization in a solvent, thereby preparing a terminal reactive poly(N-acylalkyleneimine) solution; (b) mixing a modified organopolysiloxane having an amino group at a terminal end, a side chain of its molecular chain, or both, and a solvent, thereby preparing a modified organopolysiloxane solution; (c) mixing the terminal reactive poly(N-acylalkyleneimine) solution obtained in said (a) subjecting and the modified organopolysiloxane solution obtained in said (b) mixing, thereby allowing 65 to 95 mol % of total amino groups in the modified organopolysiloxane to react with the terminal reactive poly(N-acylalkyleneimine); and (d) removing the solvent at 100 to 200° C. after completing said (c) mixing, to obtain the organopolysiloxane compound, wherein a poly(N-acylalkyleneimine) segment comprising repeating units represented by formula (I): wherein R is bonded to a terminal end of an organopolysiloxane segment, a side chain of the organopolysiloxane segment, or both, and further comprising cooling the terminal reactive poly(N-acylalkyleneimine) solution obtained in said (a) to a temperature of 60 to 10° C. before said (c).
