| titleOfInvention | Method for the manufacture of branched polysiloxanes |
| abstract | Objectives n To provide a novel method for the manufacture of branched polysiloxanes with the polysiloxane unit Si 4/2 O₂ as the branch center bonded precisely to one end of diorganosiloxanes. n Embodiment n Method for the manufacture of branched polysiloxane represented by formula (III), characterized by reacting a linear polysiloxane represented by formula (I) with a reactive polysiloxane represented by formula (II): formula (I), n n n n R¹(R²R³SiO) a M n n n n (in the formula, R¹, R² and R³ independently represent hydrogen atoms, alkyl, haloalkyl or alkenyl groups of 1-8 carbon atoms, or aryl groups; 1 ≦ a ≦ 1000; M represents an alkali metal atom or a hydrogen atom); formula (II), n n n n SiO 4/2 ) x (R⁴₂XSiO 1/2 ) Y (R⁵₂R⁶SiO 1/2 ) z (RO 1/2 ) w n n n n (in the formula, R⁴ and R⁵ represent alkyl, haloalkyl or alkenyl groups of 1-8 carbon atoms, or aryl groups; R⁶ is as defined for R¹; X represents a halogen atom; R represents a hydrogen atom or alkyl group of 1-8 carbon atoms; 2 ≦ x ≦ 500, 2 ≦ y + z + w ≦ 150; 2 ≦ y; 0 ≦ z; 0 ≦ w ≦ 15; 0.3 ≦ (y + z + w)/x ≦ 3; 0 ≦ w/(y + z + w) ≦ 0.1); nformula (III), n n n n (SiO 4/2 ) x (R⁴₂ASiO 1/2 ) y (R⁵₂R⁶SiO 1/2 ) z (RO 1/2 ) w n n n n (in the formula, A represents (OSiR²R³) a R¹). |
