Antifouling quaternary halide salts containing a triorganotin ether moiety

A quaternary salt of an aryl halide or a C.sub.8 -C.sub.24 aliphatic hydrocarbon halide and a tertiary amine containing a triorganostannyl ether moiety whose etheral oxygen atom links a triorganotin radical to a carbon atom at least two carbon atoms removed from a tertiary amino nitrogen atom of the tertiary amine, and which quaternary salt is of the formula ##STR7## wherein X is Cl, Br, or I, each R is an alkyl radical of up to 12 carbon atoms with the sum total of the carbon atoms in the three not exceeding 24, with no more than one of the three containing more than 4 carbon atoms, and with each of the three not necessarily the same R,

• R' is an aryl hydrocarbon radical, or a C.sub.8 -C.sub.24 alkyl radical, and
• Q is a quaternized moiety of a tertiary amine moiety selected from the group consisting of an aliphatic tertiary amine moiety of the structure ##STR8## wherein n is a whole integer of from 2 to 5, and a methyl radical may replace a -H for up to and including two of the -H in the --(CH.sub.2).sub.n -- chain, and R" and R'" are C.sub.1 -C.sub.10 alkyl radicals which are not necessrily the same, and a tertiary amine structural moiety including an aromatic ring of the structure ##STR9## wherein Z is the same or different and at least one Z is --NR.sub.2 or --(CH.sub.2).sub.n NR.sub.2 and any remaining Z is H, with R an alkyl radical having from 1 to 4 carbon atoms, and n is a whole number integer of from 1 to 5.
