POLYCONDENSATION OF POLYSILOXANE CONTAINING HYDROXYSILYL GROUP FROM ALKALI METAL OR ALKALI EARTH METAL AND POLYHETERO ATOM MACROPOLYCYCLIC COMPOUND

摘要

The present invention relates to a process for obtaining of polysiloxanes by reaction of polycondensation of organopolysiloxanes having groups hydroxysilyl. / p & & p & the process of the invention is characterizes in that it is used as for the catalysis of the polycondensation reaction of an alkali metal or alkaline-earth - metal associated with a polyheteromacropolycyclique (encrypting agent containing at least 2 nitrogen atoms tertiary. / p & & p & the method makes it possible to obtain, in particular, with a kinetic quickly and without the formation of polysiloxanes of masses molecular not castings, of the organopolysiloxanes of the mass is a continuation tres high.
