A binder composition contains a copolymer having both an acid and a hydroxyl, amide or amine functionality. Polyamines are used as crosslinkers for the polymer binder. The binder composition is especially useful for binding mineral fiber, and particularly as a fiberglass binder. Ideally the copolymer is methacrylic acid-co-2-hydroxyethyl methacrylate, methacrylic acid-co-dimethylaminoethyl methacrylate, acrylic-acid-co-hydroxypropyl acrylate, acid-co-hydroxyethyl acrylate, acrylic acid-co-diallyldimethyl ammonium chloride, or a carboxybetaine/sulfobetaine derivation of acrylic acid-co-vinyl pyridine. |
