<p>The preparation and use of quarternized bis hydroxy alkyl amines by the reaction of a tertiary amine and an alkylene oxide in a strong acid system are disclosed. Cationic polyurethane compositions containing pendent hydroxy alkyl groups and methods for their preparation are also disclosed, as is also a composition of matter of the formula <CHEM> wherein R and R' are each independently selected from the groups consisting of alkyls having from 1 to about 10 carbon atoms, phenyl, and substituted phenyl groups; R'' is selected from the groups consisting of hydrogen, alkyl having from 1 to about 10 carbon atoms, cycloalkyl having from 5 to 7 carbon atoms in the cycloalkyl group and aryl; R''' is selected from the groups consisting of hydrogen, methyl, ethyl, phenyl, aryl and cyano or nitro substituted alkyl groups; m and n are integers independently selected from 0 to about 15; and X is selected from the ions of an acid having a pKa of less than about 3.</p> |
