A novel polymer composition comprising recurring units of the formula: [Figure] wherein each R1 is, individually, hydrogen or C1-C4 alkyl; each R5, individually, is hydrogen or a C1-C4 lower alkyl group; X is OH or SH; Y is OR2, SR2, NR22, or NR2-NR22; R2 is hydrogen, a C1-C4 lower alkyl or a C1-C4
A novel polymer composition comprising recurring units of the formula: [Figure] wherein each R1 is, individually, hydrogen or C1-C4 alkyl; each R5, individually, is hydrogen or a C1-C4 lower alkyl group; X is OH or SH; Y is OR2, SR2, NR22, or NR2-NR22; R2 is hydrogen, a C1-C4 lower alkyl or a C1-C4 substituted lower alkyl, no more than one of Y and X being hydroxyl, and M is hydrogen, an alkali metal cation or an ammonium ion; x represents a residual mole percent fraction; y is a mole percent fraction ranging from about 0.5% to about 25%; z is a mole percent fraction ranging from about 0% to about 25%; and the molecular weight of the polymer is between about 1,000 and 500,000.
