Abstract
Hydroxysulfobetaines having the formula ##STR1## wherein Y represents two to five substituted nitrogens connected by --(CH.sub.2).sub.m -- groups, selected from the group consisting of ##STR2## WITH THE PROVISO THAT AT LEAST ONE OF Y is B); R.sub.1 is an alkyl and R.sub.2 is a member selected from the group consisting of hydrogen and alkyl, where the sum of the carbon atoms in R.sub.1 + R.sub.2 is from 9 to 22; R.sub.3 is a member selected from the group consisting of hydrogen, hydroxyethyl and alkyl having from 1 to 5 carbon atoms; R.sub.4, R.sub.5 and R.sub.6 are individually members selected from the group consisting of hydroxyethyl and alkyl having from 1 to 5 carbon atoms; R.sub.7 is a member selected from the group consisting of ##STR3## and R.sub.4 ; X.sup..crclbar. is a member selected from the group consisting of --(CH.sub.2).sub.n -- SO.sub.3.sup..crclbar. and --CH.sub.2 -- CH(OH) -- CH.sub.2 -- SO.sub.3.sup..crclbar. ; m is an integer from 2 to 6; n is an integer from 1 to 4; (anion).sup..crclbar. represents an anionic group; and (cation).sup..sym. represents a cationic group, as well as the method of making fiber materials antistatic by applying an above hydroxysulfobet…
