FOERFARANDE FOER REGLERING AV MOLEKYLMASSA AV POLYCHLOROFOSFAZENER OCH DAERAV HAER LEDDA POLYORGANOFOSFAZENER OCH REGLERINGSMEDEL ATT ANVAENDAS VID DETTA FOERFARANDE.

摘要

The invention relates to a process for the preparation of polychlorophosphazene. According to this process the molecular mass of the polymers is adjusted at will by performing the reaction of the polycondensation of N(dichlorophosphoryl)trichlorophosphazene in the presence of the product of reaction of such a monomer with an organic alkali metal salt. This technique makes it possible to prepare reproducibly uncrosslinked polymers which have the molecular mass desired as a function of the applications for which they are intended.
