Claim:
A glass binding composition comprising a copolymer derived from a monomer mixture comprising: about 30 to about 99.99 percent by weight of at least one acid functional monomer unit selected from the group consisting of acrylic acid, methacrylic acid, maleic acid, 2-acrylamidomethyl propane sulfonic acid, styrene sulfonic acid, (meth)allyl sulfonic acid, (meth)allyloxybenzene sulfonic acid or mixtures thereof; about 0.01 to about 30 percent by weight of at least one silanol monomer as a comonomer unit; and about 0 to about 50 percent by weight of at least one ethylenically unsaturated monomer unit, wherein the copolymer is soluble in water; and a crosslinker.
