Procedure

By the same synthesis procedure as for (3c) in Example 1, the above (2a) was reduced to obtain 1,3-bis(4-aminophenoxybutyl)-1,1,3,3,-tetramethyldisiloxane (3a) (a light brown oily liquid (98% of yield)) represented by the following formula. Various measurements were carried out with regard to the obtained 1,3-bis(4-aminophenoxybutyl)-1,1,3,3,-tetramethyldisiloxane (3a), and results are shown below.
