THE PRESENT INVENTION PROVIDES AN ORGANOPOLYSILOXANE OBTAINED BY BINDING, TO AT LEAST TWO SILICON ATOMS OF AN ORGANOPOLYSILOXANE SEGMENT CONSTITUTING A MAIN CHAIN, A POLY (N-ACYLALKYLENEIMINE) SEGMENT COMPOSED OF A REPEATING UNIT REPRESENTED BY THE FOLLOWING FORMULA (1): WHEREIN R1 REPRESENTS A HYDROGEN ATOM OR AN ALKYL GROUP HAVING FROM 1 TO 3 CARBON ATOMS AND N IS 2 OR 3, VIA AN ALKYLENE GROUP CONTAINING A HETERO ATOM, WHEREIN THE POLY(N-ACYLALKYLENEIMINE) SEGMENT HAS A NUMBER-AVERAGE MOLECULAR WEIGHT OF FROM 1,600 TO 3,500; A MASS RATIO (A/B) OF THE ORGANOPOLYSILOXANE SEGMENT (A) CONSTITUTING THE MAIN CHAIN TO THE POLY(N-ACYLALKYLENEIMINE) SEGMENT (B) (WHICH WILL HEREINAFTER BE CALLED ?MASS RATIO (A/B)?, SIMPLY) IS FROM 42/58 TO 58/42; THE ORGANOPOLYSILOXANE SEGMENT BETWEEN TWO POLY(N-ACYLALKYLENEIMINE) SEGMENTS ADJACENT TO EACH OTHER HAS A WEIGHT-AVERAGE MOLECULAR WEIGHT OF FROM 1,600 TO 3,500; AND THE ORGANOPOLYSILOXANE SEGMENT CONSTITUTING THE MAIN CHAIN HAS A WEIGHT-AVERAGE MOLECULAR WEIGHT OF 7,000 TO 100,000. |
