Abstract

Abstract Novel sulfate compounds of the formula: R-(C)m-(D)n-(CH2)v-(OSO2)u-O-(CH2)v-(D)n-(C)m-R wherein R is a polyhaloisoalkoxyalkyl group having the formula: and wherein C is a bifunctional group which may be derived from a telomerizable acetylenically or ethylenically unsaturated compound, m is an integer from 0-75, D is a bifunctional group which may be derived from a telomerizab acetylenically or ethylenically unsaturated compound, n is integer from 0-75, u is an integer of from 1-6 and v is an integer of from 0-1; with the proviso that each carbon ato which is directly bonded to the -(OSO2)u-0- moiety, contai least one hydrogen atom, are prepared by reacting a polyhaloisoalkoxyalkyl halide corresponding to the general formula: and wherein C is a bifunctional group which may be derived from a telomerizable acetylenically or ethylenically unsaturated compound, m is an integer from 0-75, D is a bifunctional group which may be derived from a telomerizable acetylenically or ethylenically unsaturated compound, n is an integer from 0-75, u is an integer of from 1-6 and v is an integer of from 0-1; with the proviso that each carbon atom which is directly bonded to the -(OSO2)u-0- moiety, contains at least one hydrogen atom, are prepared by reacting a polyhaloisoalkoxyalkyl halide corresponding to the general formula: WHEREIN: A. R1 and R2 are F, Cl, alkyl or haloalkyl groups or, when taken together, are alkylene or haloalkylene groups forming a cycloaliphatic structure, which R1 and R2 groups may each have from 1 to 9 carbon atoms and which halogen atoms, if any, have an atomic weight not exceeding about 79.92, with the proviso that no more than two of the four R1 and R2 groups are alkyl groups and B. A is a member selected from the group consisting of radicals of the formulae: -CHR3-CHR4-, CFR5-CR6R7- and
