YieldReaction ConditionsOperation in experiment
at 20 - 60℃; for 4h; 286.50 parts of 3-aminopropyldiethoxymethylsilane were mixed with 505.40 parts of the freshly prepared organic phase from 1.1 with stirring at room temperature and heated to 60° C. An exothermic reaction took place, during which the temperature was kept at 60° C. by cooling. As soon as the exothermic reaction had passed, the mixture was left to react further for 4 hours at 60° C. and only then cooled to room temperature. Glycidyl groups could no longer be titrated. This was because alkylation of the primary amino groups of the silane had taken place. This thus gave 791.9 parts of a silane mixture (II) with the following main components:

YieldReaction ConditionsOperation in experiment
Arninofunctional Silicone Resins A1-A9 were prepared in the following manner. A mixture of phenyltrimethoxysilane, phenylmethyldimethoxysilane, gamma-aminopropyltriethoxysilane (APTES), and/or gamma-aminopropyldiethoxymethylsilane (APDEMS) was optionally dissolved in aromatic solvent and hydrolyzed with deionized water, followed by distillative removal of by-product alcohol. The resulting structure was optionally reacted with trimethylethoxysilane, hexamethyldisilazane (HMDZ), APDEMS and/or dimethyldimethoxysilane, additional solvent and additional water added, a catalytic amount of aqueous potassium hydroxide optionally added and the water removed via azeotrope. The hydroxide, if added, was neutralized with aqueous HCl or acetic acid, and water removed again via azeotrope. The mixture was filtered and solvent removed to yield silicone resin product. The amount of each ingredient is shown in Table 1 below. The final aminofunctional silicone resin composition, wt percent phenyl (Ph), wt percent R2SiO (D), wt percent Me2SiO (D(Me2)), mole percent amino (-CH2CH2CH2NH2), wt percent amine (-NH2), and -NH- (Amine H) equivalent weight are shown in Table 2 below.

A mixture of phenyltrimethoxysilane, phenylmethyldimethoxysilane, gamma-aminopropyltriethoxysilane (APTES), and/or gamma-aminopropyldiethoxymethylsilane (APDEMS) was optionally dissolved in aromatic solvent and hydrolyzed with deionized water, followed by distillative removal of by-product alcohol. The resulting structure was optionally reacted with trimethylethoxysilane, hexamethyldisilazane (HMDZ), APDEMS and/or dimethyldimethoxysilane, additional solvent and additional water added, a catalytic amount of aqueous potassium hydroxide optionally added and the water removed via azeotrope. The hydroxide, if added, was neutralized with aqueous HCl or acetic acid, and water removed again via azeotrope. The mixture was filtered and solvent removed to yield silicone resin product. The amount of each ingredient is shown in Table 1 below. The final aminofunctional silicone resin composition, wt percent phenyl (Ph), wt percent R2SiO (D), wt percent Me2SiO (D(Me2)), mole percent amino (-CH2CH2CH2NH2), wt percent amine (-NH2), and -NH- (Amine H) equivalent weight are shown in Table 2 below.
