Method for the preparation of organopolysiloxane by polymerization and rearrangement of cyclic siloxanes |
摘要 |
The invention relates to silicon oils, more particularly, to a novel method for the preparation of a silicon oil by polymerization and rearrangement of cyclic siloxanes in the presence of an alkaline catalyst and a co-catalyst which is a cryptand (macroheterobicyclic diamine) acting as a polymerization accelerator.
