Title:
CROSSLINKABLE SULFONATED AROMATIC POLYAMIDE AND POLYUREA
Document Type and Number:
Japanese Patent JPH02300231
Kind Code:
A
Abstract:
PURPOSE: To obtain a water-soluble and water-dispersible, i.e., water-compatible polymer which is useful for an oil recovering rate improver in digging of oil well, etc., a thickener for paints, etc., a sizing agent for fabrics, etc., by selecting a specified polymer with amide or urea repeating bond units.
CONSTITUTION: A polymer with amide or urea repeating bond units corresponding to formula I {wherein Y is a compatible substituent; M+ is a compatible cation; Z is a group of formulas II-IV [wherein R1 is an (inactive substd.) hydrocarbilene]; R2 is a covalent bond and R1} (e.g. a polymer obtd. by reacting 4,4'-diaminobiphenyl-2,2'-disulfonic acid with terephthaloyl chloride) is selected.
