| titleOfInvention | Method for preparation of organopolysilixame having branched molecular structure |
| abstract | The invention discloses a method for the preparation of an organopolysiloxane having a branched molecular structure which comprises the steps of: n (A) mixing n (A1) an organopolysiloxane represented by the average unit formula n [R 1 3 SiO ½ ] m[R 1 SiO {fraction (3/2)} ] n [R 1 (R 2 O) SiO] q , n in which R 1 is a monovalent hydrocarbon group, R 2 is a hydrogen atom, methyl group or ethyl group and the subscripts m, n and q are each 0 or a positive number with the proviso that (n+q)/m is from 0.6 to 1.5 and q/(m+n) is 0 or a positive number not exceeding 0.05; n (A2) a cyclic dialkylsiloxane oligomer, and n (A3) a polyorganosiloxane represented by the structural formula n R 3 3 Si—O—(—SiR 3 2 —O—) r —SiR 3 3 , n In which R 3 is a monovalent hydrocarbon group and the subscript r is 0 or a positive integer not exceeding 100, to give a siloxane mixture; n (B) admixing the siloxane mixture with an alkaline compound; and n (C) heating the siloxane mixture to effect siloxane rearrangement polymerization of the organopolysiloxanes. |
