Abstract
Cationic bis(trimethylsiloxy) siloxanes of the formula: EQU MD.sub.x' M wherein M is the trimethylsiloxy units, Me.sub.3 SiO.sub.1/2, x is an integer of 1 to 3, preferably 1, and D' is a cationic difunctional siloxy unit of the formula: ##STR1## wherein R.degree. is a divalent organic group, t is 0 to 1, R is methyl or ethyl, R.sub.2 N is a five to six member organic heterocyclic ring and X is an anion. Also the tertiary amino bis(trimethylsiloxy) siloxanes of the formula MD.sub.x M wherein M and x are as defined above and D is a tertiary amino difunctional siloxy unit of the formula: EQU R.sub.2 NR.degree.(O).sub.t Si(Me)O wherein R.sub.2 N, R.degree. and t are as defined above, which are used in preparing the above cationic siloxanes. The above cationic siloxanes are useful as emulsifiers, e.g., for water-poly(dimethylsiloxane) oil systems, bacteriocides, antistatic agents, wetting agents and mold release agents.
