| titleOfInvention | Process for the preparation of silarylenesiloxane-diorganosiloxane copolymers |
| abstract | Linear-chain copolysiloxanes comprising units of the general formulae (1) and (2), n [—(R 1 R 2 SiO) a —] (1), n [—(R 3 R 4 Si—R 7 —SiR 5 R 6 O) b —R 3 R 4 Si—R 7 —SiR 5 R 6 —] (2), n the end-groups of which may be Si—H or Si—OH, are prepared by reacting: n (A) diorganopolysiloxanes of the general formula (3) n HO—(R 1 R 2 SiO) a —H (3) n with n (B) silarylenesiloxane compounds of the general formula (4) n H—[(R 3 R 4 Si—R 7 —SiR 5 R 6 O) b —R 3 R 4 Si—R 7 —SiR 5 R 6 ]—H (4), n in the presence of (C) a transition metal catalyst, wherein R 1 , and R 2 are optionally substituted and optionally heteroatom-containing hydrocarbon radicals, R 3 , R 4 , R 5 , and R 6 are optionally halogen-substituted and optionally heteroatom-containing aliphatically or aromatically unsaturated C 1-20 hydrocarbon radicals, and R 7 is an aromatic, optionally substituted, and optionally heteroatom-containing divalent hydrocarbon radical. The copolysiloxanes are well defined, and have internal blocks corresponding to the (3) and (4) starting materials, substantially free of rearrangement and equilibration products. |
