PROCESS FOR THE PREPARATION OF POLYDICHLOROPHOSPHAZENES COMPOSITIONS AT CONTROL RATES OF CYCLIC OLIGOMERS AND THE COMPOSITIONS RESULTING FROM THE IMPLEMENTATION OF SAID METHOD

摘要

The subject of the invention is a process for the preparation of polydichlorophosphazenes compositions containing a controlled content of cyclic oligomers. /P P The control of this content is obtained by action on the concentration of the monomer (P2 NO Cl5 or P2 NS Cl5) in the solution of said polycondensation monomer. /P P The invention also relates to compositions containing said controlled rate of cyclic oligomers.
