ABSTRACT:
Disclosed are novel crosslinked polymeric ammonium salts wherein in said salt: about 25% or more of the groups which link ammonium nitrogen atoms are group Y wherein Y is an-alkylene groups or alkyl substituted n-alkylene group, wherein said n-alkylene group has 7 to about 20 carbon atoms; zero to about 75% of groups which links ammonium nitrogen atoms are group Z wherein Z is a hydrocarbylene radical containing 2 or more carbon atoms, said hydrocarbylene radical optionally containing one or more hydroxyl, ether, amino, thioether, keto, or silyl groups or heterocyclic rings; and about 25% or more of the ammonium atoms are secondary ammonium atoms.
