Process for making organopolysiloxanes

Claim 1

A METHOD FOR EFFECTING THE INTERCONDENSATION AND REARRANGEMENT OF SILOXY UNITS HAVING CARBOXYALKYL RADICALS ATTACHED TO SILICON BY CARBON-SILICON LINKAGES TO PROVIDE FOR THE FORMATION OF CARBOXYALKYLORGANOPOLYSILOXANE HAVING A RATIO OF THE SUM OF CARBOXYALKYL RADICALS AND ORGANO RADICALS PER SILICON ATOM OF FROM 1.5 TO 3, AND A VISCOSITY UP TO 10**8 CENTIPOISES AT 25*C, WHICH COMPRISES HEATING AT A TEMPERATURE BETWEEN 20* TO 170*C, A MIXTURE OF CARBOXYALKYLPOLYSILOXANE AND 0.01% TO 10% BY WEIGHT THEREOF OF AN EQUILIBRATION CATALYST, WHERE SAID CARBOXYALKYLPOLYSILOXANE IS SELECTED FROM. (A) CARABOXYALKYLPOLYSILOXANE CONSISTING ESSENTIALLY OF CHEMICALLY COMBINED SILOXY UNITS HAVING CARBOXYALKYL RADICALS ATTACHED TO SILICON, AND (B) A MIXTURE OF SAID CARBOXYALKYLPOLYSILOXANE AND ORGANOSILOXANE CONSISTING ESSENTIALLY OF CHEMICALLY COMBINED SILOXY UNITS HAVING ORGANO RADICALS ATTACHED TO SILICON, SELECTED FROM THE GROUP CONSISTING OF MONOVALENT HYDROCARBON RADICALS, HALOGENATED MONOVALENT HYDROCARBON RADICALS AND CYANOALKYL RADICALS, AND SAID EQUILIBRATION CATALYST IS THE PRODUCT OF REACTION AT A TEMPERATURE IN THE RANGE OF FROM -10*C TO 100*C OF 0.1 TO 400 PARTS OF A HYDROXY CONTAINING MATERIAL, PER PART OF A PHOSPHOROUS HALOGEN COMPOUND SELECTED FROM THE CLASS CONSISTING OF PHOSPHORUS PENTAHALIDES AND PHOSPHOROUS OXY HALIDES, WHERE SAID HYDROXY CONTAINING MATERIAL IS SELECTED FROM THE CLASS CONSISTING OF SECONDARY ALIPHATIC ALCOHOLS, TERTIARY ALIPHATIC ALCOHOLS, ALIPHATIC CARBOXYLIC ACIDS, AND ACIDS OF PHOSPHOROUS HAVING HYDROXY RADICALS ATTACHED TO PHOSPHOROUS.

Claim 2

A METHOD FOR EFFECTING THE INTERCONDENSATION AND REARRANGEMENT OF SILOXY UNITS HAVING CARBOXYALKYL RADICALS ATTACHED TO SILICON BY CARBON-SILICON LINKAGES TO PROVIDE FOR THE FORMATION OF CARBOXYALKYLORGANOPOLYSILOXANE HAVING A RATIO OF THE SUM OF CARBOXYALKYL RADICALS AND ORGANO RADICALS PER SILICON ATOM OF FROM 1.5 TO 3, AND A VISCOSITY UP TO 10**8 CENTIPOISES AT 25*C, WHICH COMPRISES HEATING AT A TEMPERATURE BETWEEN 20* TO 170*C, A MIXTURE OF CARBOXYALKYLPOLYSILOXANE AND 0.01% TO 10% BY WEIGHT THEREOF OF AN EQUILIBRATION CATALYST, WHERE SAID CARBOXYALKYLPOLYSILOXANE IS SELECTED FROM. (A) CARABOXYALKYLPOLYSILOXANE CONSISTING ESSENTIALLY OF CHEMICALLY COMBINED SILOXY UNITS HAVING CARBOXYALKYL RADICALS ATTACHED TO SILICON, AND (B) A MIXTURE OF SAID CARBOXYALKYLPOLYSILOXANE AND ORGANOSILOXANE CONSISTING ESSENTIALLY OF CHEMICALLY COMBINED SILOXY UNITS HAVING ORGANO RADICALS ATTACHED TO SILICON, SELECTED FROM THE GROUP CONSISTING OF MONOVALENT HYDROCARBON RADICALS, HALOGENATED MONOVALENT HYDROCARBON RADICALS AND CYANOALKYL RADICALS, AND SAID EQUILIBRATION CATALYST IS THE PRODUCT OF REACTION AT A TEMPERATURE IN THE RANGE OF FROM -10*C TO 100*C OF 0.1 TO 400 PARTS OF A HYDROXY CONTAINING MATERIAL, PER PART OF A PHOSPHOROUS HALOGEN COMPOUND SELECTED FROM THE CLASS CONSISTING OF PHOSPHORUS PENTAHALIDES AND PHOSPHOROUS OXY HALIDES, WHERE SAID HYDROXY CONTAINING MATERIAL IS SELECTED FROM THE CLASS CONSISTING OF SECONDARY ALIPHATIC ALCOHOLS, TERTIARY ALIPHATIC ALCOHOLS, ALIPHATIC CARBOXYLIC ACIDS, AND ACIDS OF PHOSPHOROUS HAVING HYDROXY RADICALS ATTACHED TO PHOSPHOROUS.
