Fiberglass mats, binder compositions, and methods for making the same are provided. In at least one specific embodiment, the fiberglass mat can include a plurality of glass fibers and a binder composition that includes a copolymer and one or more amines. The copolymer can include one or more unsaturated carboxylic acids, one or more unsaturated carboxylic anhydrides, or a combination thereof, and one or more vinyl aromatic derived units. The binder composition can have a weight average molecular weight (Mw) of about 500 to about 180,000. The fiberglass mat can have a thickness ranging from about 10 mils to about 1,000 mils, an average dry tensile strength of at least 50 lbs/3 inch; and an average Elmendorf tear strength of at least 300 gf.
