Abstract
Novel hydrophilic modified acrylic polymers, which are, in particular, hydrosoluble or hydrodispersible. These novel polymers contain, expressed in molar percentages, p % of units derived from an acrylic acid or ester, q % of units derived from an alkanolamine of said acid, r % of units derived from the alkali metal, alkaline earth metal or ammonium salt of the said acid, and s % of units derived from a vinylic monomer, p, q, r and s representing integers and being so selected that 1.ltoreq.p.ltoreq.99, O.ltoreq.q.ltoreq.96, O.ltoreq.r.ltoreq.99 and O.ltoreq.s.ltoreq.40, and the sum (p+q+r+s) is equal to 100.
