Method of polymerizing siloxanes and silcarbanes in emulsion by using a surface active sulfonic acid catalyst

Claim 1

AN AQUEOUS EMULSION OF A POLYMER CONTAINING THE UNIT FORMULA

Claim 2

A METHOD WHICH COMPRISES POLYMERIZING AND COPOLYMERIXING (1) AT LEAST ONE MEMBER SELECTED FROM THE GROUP CONSISTING OF ORGANOSILOXANES OF THE UNIT FORMULA RNSIO4-N/2 IN WHICH R IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN ATOMS, MONOVALENT HYDROCARBON RADICALS AND MONOVALENT HALOHYDROCARBON RADICALS AND N HAS AN AVERAGE VALUE OF FROM 0.5 TO LESS THAN 3, AND SILCARBANES HAVING THE GENERAL FORMULA HO(R)2SIQSI(R)2OH WHEREIN R IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN ATOMS, MONOVALENT HYDROCARBON RADICALS AND MONOVALENT HALOHYDROCARBON RADICALS AND Q IS A DIVALENT RADICAL ATTACHED TO BOTH SILICON ATOMS VIA A SILICON-CARBON BOND, SAID Q BEING SELECTED FROM THE GROUP CONSISTING OF RADICALS COMPOSED OF CARBON AND HYDROGEN ATOMS AND RADICALS COMPOSED OF CARBON, HYDROGEN AND OXYGEN ATOMS, THERE BEING LESS THAN 15 CARBON ATOMS IN SAID Q RADICAL AND ANY OXYGEN THAT IS PRESENT BEING IN THE FORM OF ETHER LINKAGES, BY POLYMERIZING SAID MEMBER IN AN AQUEOUS MEDIUM WHILE IN A DISPERSED STATE IN THE PRESENCE OF (2) A SURFACE ACTIVE SULFONIC ACID SELECTED FROM THE GROUP CONSISTING OF THE ALIPHATICALLY SUBSTITUTED BENZENE-SULFONIC ACID CONTAINING AT LEAST SIX CARBON ATOMS IN THE ALIPHATIC SUBSTITUENTS, THE ALIPHATICALLY SUBSTITUTED NAPTHALENSULFONIC ACIDS CONTAINING AT LEAST FOUR CARBON ATOMS IN THE ALIPHATIC SUBSTITUENTS, THE ALIPHATIC SULFONIC ACIDS CONTAINING AT LEAST SIX CARBON ATOMS IN THE ALIPHATIC SUBSTITUENT, THE SILYLALKYLSULFONIC ACIDS CONTAINING AT LEAST SIX CARBON ATOMS IN THE ALKYL SUBSTITUENTS, AND THE ALIPHATICALLY SUBSTITUTED DIPHENYLETHERSULFONIC ACIDS CONTAINING AT LEAST SIX CARBON ATOMS IN THE ALIPHTIC SUBSTITUENTS, AS THE PRIMARY POLYMERIZATION CATALYST, UNTIL THE DESIRED INCREASE IN MOLECULAR AGGREGATION IS OBTAINED.
