Abstract
Fiberglass mats, binder compositions, and methods for making the same are provided. The fiberglass mat can include a plurality of glass fibers and an at least partially cured binder composition. The binder composition, prior to at least partial curing, can include a first copolymer modified by reaction with one or more base compounds. The first 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 first copolymer can have a weight average molecular weight (Mw) of about 500 to about 200,000. The first copolymer can be present in an amount ranging from about 60 wt % to about 95 wt %, based on a combined weight of the first copolymer and the one or more base compounds.
