CROSSLINKED POLYMERIC AMMONIUM SALTS |
摘要 |
Disclosed are novel crosslinked polymeric ammonium salts wherein in said pol ymeric salt: about 25 % or more of the segments which link ammonium nitrogen atoms are group Y wherein Y is an n-alkylene gr oup or alkyl substituted n-alkylene group, wherein said n-alkylene group has 7 to about 20 carbon atoms; zero to about 75 % of segme nts which link ammonium nitrogen atoms are group Z wherein Z is a hydrocarbylene radical containing 2 or more carbon atoms, sai d hydrocarbylene radical optionally containing one or mo re hydroxyl, ether, amino, thioether, keto, or silyl groups or heterocyclic rin gs; and about 25 % or more of the ammonium atoms are sec ondary ammonium atoms.
