Abstract
Abstract This invention is directed to telomeric quaternary salt compositions of the formula [A.sub.x B.sub.y ].sub.Z wherein A is a segment selected from vinyl monomers, B is a quaternary salt segment, x and y are numbers representing mole fractions of A and B, the sum of x and y being equal to 1, and Z represents the degree of polymerization, wherein there results a telomeric quaternary salt having a number average molecular weight of from about 1,000 to about 10,000.

Claim 2
Dependent Claim
79 words
A telomeric quaternary salt composition of the formula [A.sub.x B.sub.y ].sub.Z wherein A is styrene, and B is selected from a quaternized salt prepared from 2-vinylpyridine, 3-vinylpyridine, 4-vinylpyridine, and dimethylaminoethylmethacrylate, x and y are numbers representing mole fractions of A and B, the sum of x and y being equal to 1, and Z represents the degree of polymerization, wherein there results a polymeric quaternary salt having a number average molecular weight of from about 1,000 to about 10,000.
