CATALYST TO MANUFACTURE ORGANOSILOXANES OR POLIORGANOSILOXANES.

摘要

THE INVENTION REFERS TO A CATALYST FOR THE ELABORATION OF ORGANOSILOXANES AND POLIORGANOSILOXANES, WHICH ARE OBTAINED MAINLY THROUGH POLYCONDENSATION PROCESSES. THE CATALYST ACCORDING TO THE INVENTION IS A TRANSFORMATION PRODUCT OF PHOSPHONITRILE CHLORIDE WITH A COMPOUND OF THE GENERAL FORMULA [R {SUB, 3} SIO (R {SUB, 2} SIO) {SUB, M] {SUB, 3} P = 0 (I), WHERE R INDEPENDENTLY ONE OF THE OTHER MAY BE THE SAME OR DIFFERENT, BEING REMAINS OF SATURATED AND / OR NOT SATURATED HYDROCARBON WITH 1 TO 6 ATOMES OF CARBON OR HYDROGEN WITH THE CONDITION OF SOLIGOMATE THAT IS OF HYDROGEN FOR EACH ATOM OF SILICON AND M IS A VALUE BETWEEN 0 AND 1,000. VOLATILE CHLORINE CONTAINING SILICON COMPOUNDS FORMING DURING REACTION MAY BE COMPLETELY OR PARTIALLY REMOVED IF NECESSARY.
