摘要：
The present invention provides near quantitative yields of greater than about 95% isomeric purity of poly(3-aminopropylmethylsiloxane)-poly(dimethylsiloxane) copolymers of the general formulae: Me3Si(H2NCH2CH2CH2MeSiO)w(Me2SiO)xOSiMe3 (H2NCH2CH2CH2MeSiO)y(Me2SiO)z wherein Me is methyl, w may range from 1 to about 100, x may range from 1 to about 100, y may range from 1 to about 6, z may range from 1 to about 6 and y+z may range from 3 to about 7. The present invention also provides a simple method for rapidly producing poly(3-aminopropylmethylsiloxane)-poly(dimethylsiloxane) copolymers of the general formulae: Me3Si(H2NCH2CH2CH2MeSiO)w(Me2SiO)xOSiMe3 (H2NCH2CH2CH2MeSiO)y(Me2SiO)z wherein Me is methyl, w may range from 1 to about 100, x may range from 1 to about 100, y may range from 1 to about 6, z may range from 1 to about 6, and y+z may range from 3 to about 7, the method comprising heating of poly(3-aminopropylmethylsiloxane) of at least 95% isomeric purity, a cyclodimethylsiloxane with a basic catalyst, and destroying the catalyst when the copolymerization reaction is complete.
