发明名称 Siloxane block-copolymers
摘要 <p>Preparation of organopolysiloxane (A) comprises adding organopolysiloxane (I) (6-folds molecular excess) with vinylsiloxane (II) in the presence of platinum/rhodium catalyst; adding transition metal-catalyzed silicon hydride (SiH) groups of alkenyl/alkynyl compounds to the reaction product; and partially/completely reacting the RSiH groups (obtained from the above reaction) with at least an alcohol, in the presence of a catalyst. Preparation of organopolysiloxane (A) comprises adding organopolysiloxane of formula (I) (6-folds molecular excess) with vinylsiloxane (II) of formula (CH 2=CH-Si(R1 2)-O-[Si(R1 2)-O] d-Si(R1 2)-CH=CH 2) in the presence of platinum/rhodium catalyst; adding transition metal-catalyzed silicon hydride (SiH) groups of alkenyl/alkynyl compounds to the reaction product (where the remaining RSiH-groups with at least one alcohol, aromatic, aliphatic-aromatic, optionally halogen atoms of mono alcohols, polyethermonoalcohol, polyester mono alcohols or aminoalcohol); and partially/completely reacting the RSiH groups (obtained form the above reaction) with at least an alcohol from optionally saturated aromatic, aliphatic-aromatic, optionally halogen atom containing mono alcohols, polyethermonoalcohol, polyester monoalcohol or aminoalcohol, in the presence of a catalyst. R1 : H, or 1-20C aliphatic or aromatic hydrocarbon; R2 : H; a : 5-500; b : 1-50; c : 0-5 (preferably 0); and d : 10-1000. Provided that at least three residues of R1 and R2 are H. [Image].</p>
