Embodiment 1

[0131] Condensed by hydrolysis [CH 2 =CH-C 6 h 4 -CH 2 -NH-(CH 2 ) 2 NH(CH 2 ) 3 Si(OCH 3 ) 3 ]HCl(VIb) to prepare amino-functional polysiloxane

[0132] In a heatable 2-1-three-necked flask equipped with a nitrogen stacking device, a distillation device and a dropping funnel, 750 g of a 50% by weight methanol solution of VI (3.74% by weight of silicon) was preliminarily placed. Next, 27 g of water (corresponding to 1.5 mol of water per mol of silicon used) was slowly added with stirring. 27 g of methanol were then removed from the reaction mixture by distillation at ambient pressure. The solution was then heated to 60°C for about 3 hours. The solution had a silicon content of 3.74% by weight.

Embodiment 2

[0134] Condensation by hydrolysis [C 6 h 5 -CH 2 -NH-(CH 2 ) 2 NH(CH 2 ) 3 Si(OCH 3 ) 3 ]HCl(VIc) to prepare functionalized aminopolysiloxane

[0135] Into a heatable 2-1-three-necked flask equipped with a nitrogen stacking device, a distillation device and a dropping funnel, 697 g of a 50% by weight methanol solution of VII (4.01% by weight of silicon) was placed in advance. Next, 27 g of water (corresponding to 1.5 mol of water per mol of silicon used) was slowly added with stirring. 27 g of methanol were then removed from the reaction mixture by distillation at ambient pressure. The solution was then heated to 60°C for about 3 hours. The solution had a silicon content of 4.01% by weight.

Embodiment 3

[0137] NH condensed by hydrolysis 2 -(CH 2 ) 2 NH(CH 2 ) 3 Si(OCH 3 ) 3 (VId) and with CH 2 =CH-C 6 h 4 -CH 2 Preparation of Functionalized Aminopolysiloxane by Reaction of -Cl(VIIa)

[0138] 222 g of aminoethylaminopropyltrimethoxysilane was pre-placed in a heatable 1-1-three-necked flask equipped with a nitrogen stacking device, a reflux cooler and a dropping funnel. Then 27 g of water (corresponding to 1.5 mol per mol of silicon used) were added slowly with stirring. The reaction mixture was heated to about 60°C. The temperature was maintained by heating for 1 hour. Then 105 g of methanol was added. Then 152.5 g of vinylbenzyl chloride mixed with 104.5 g of methanol was slowly added with stirring. The temperature was maintained at 64°C by cooling (during the addition) and subsequent heating for about 3 hours. After cooling, the silicon content was diluted to 3.74% by weight with 138 g of methanol.
