ABSTRACT:
Novel hydrophilic modified acrylic polymers, particularly hydrodispersible or hydrosoluble modified acrylic polymers, containing, expressed in molar percentages, p % units derived from an acrylic acid or ester, q % units derived from an alkanolamide of said acid, r % units derived from the alkanolammonium salt of said acid, and s % units derived from a vinyl monomer, wherein p, q, r, s represent integers so selected that 1.ltoreq.p.ltoreq.95, O.ltoreq.q.ltoreq.99, O.ltoreq.r.ltoreq.99 and O.ltoreq.s.ltoreq.40, the sum (p+q+r+s) being equal to 100, and q and r never being nil simultaneously.
