Heterocyclic nitrogen containing siloxanes

Claim 1

A cationic bis(trimethylsiloxy) siloxane having the formula MD s 'M wherein M is a trimethylsiloxy unit, Me 3 SiO 1/2 ,x is an integer of 1 to 3 and D' is a cationic difunctional unit having the formula: ##STR12## wherein R° is a divalent organic group, free of aliphatic unsaturation and having 2 to 18 carbon atoms, selected from the class consising of divalent hydrocarbon groups and hydroxy-substituted divalent hydrocarbon groups; R is selected from the class consisting of methyl and ethyl; R 2 N is an organic heterocyclic radical selected from the group consisting of morpholinium, piperdinum, pyrrolium, and piperazinium, said heterocyclic radical being bonded through the N atom in the above formula to the R and R° groups; X is an anion selected from the class consisting of chlorine, iodine, bromine, aryl sulfonate having 6 to 18 carbon atoms, nitrate, nitrite and borate anions when taken individually, sulfate and sulfite anions when two X - groups are taken together and a phosphate anion when three X - groups are taken together; and t is an integer of 0 to 1, with the proviso that when t is 1, R° can also be a group of the formula --R"OR"-- wherein R" is selected from the class consisting of divalent hydrocarbon groups and hydroxy-substituted divalent hydrocarbon groups as defined above.
