PURPOSE: To obtain organopolysiloxane having excellent solubility in various solvents by reacting organopolysiloxane containing primary amino group or mercapto group within molecule with specific poly(N-aoylalkyleneimine). n CONSTITUTION: (A) Organopolysiloxane containing primary amino group or mercapto group within molecule (e.g., a compound expressed by formula I) is reacted with (B) poly(N-acylalkyleneimine) obtained by ring-opening polymerization of cyclic iminoether compound expressed by formula II (R 1 is R, 1-22C alkyl, cycloalkyl, aralkyl or aryl) n is 2 or 3) to afford the aimed organopolysiloxane. n COPYRIGHT: (C)1990,JPO&Japio |
