Abstract 1. AN IMPROVED PROCESS FOR PREPARING HIGH MOLECULAR WEIGHT ORGANOPOLYSILOXANES BY MIXING ORGANOSILICON COMPOUNDS SELECTED FROM THE GROUP CONSISTING OF DIORGANOPOLYSILOXANES HAVING SI-BONDED HYDROXYL GROUPS, DIORGANOSILANOLS, TRIORGANOSILOXY END-BLOCKED DIORGANOPOLYSILOXANES, CYCLIC DIORGANOSILANES CONTAINING HYDROLYZABONOXY SILANES AND ORGANOSILANES CONTAINING HYDROLYZABLE HALIDES, WITH A PHOSPHONITRILE CHLORIDE SOLUTION, THE IMPROVEMENT WHICH COMPRISES CONTINUOUSLY MIXING TGE ORGANOSILICON COMPOUNDS WITH A PHOSPHONITRILE CHLORIDE SOLUTION OBTAINED FROM THE REACTION OF TWO MOLS OF PHOSPHOROUS PENTACHLORIDE, AND ONE MOLE OF AMMONIUM CHLORIDE UNTIL THE FORMATION OF HYDROCHLORRIC ACID HAS TERMINATED.
