| 摘要 |
The present invention provides near quantitative yields of greater than abou t 95% isomeric purity of poly(3-aminopropylmethylsiloxanes) of the general formulae: Me3Si(H2NCH2CH2CH2MeSiO)x OSiMe3 (H2NCH2CH2CH2MeSiO)y wherein Me is methyl, x may range from 2 to about 100 and y may range from 3 to about 7. The present invention also provides a simple method for rapidly producing poly(3-amino- propylmethylsiloxanes) of the general formulae: Me3Si(H2NCH2CH2CH2MeSiO)x OSiMe3 (H2NCH2CH2CH2MeSiO)y wherein Me is methyl, x may range from 2 to over 100 and y may range from 3 to about 7, the method comprising heating of 3-(3-aminopropyl)-1,1,1,3,5,5,5- heptamethyltrisiloxane, of at least 95% isomeric purity, with a basic catalyst, removing hexamethyldisiloxane, and decomposing the catalyst.
