BINDER COMPOSITIONS FOR MAKING FIBERGLASS PRODUCTS
First Claim
1. A fiberglass mat, comprising:
- a plurality of glass fibers; and
a binder composition comprising;
a copolymer comprising one or more unsaturated carboxylic acids, one or more unsaturated carboxylic anhydrides, or a combination thereof, and one or more vinyl aromatic derived units; and
one or more amines,wherein the binder composition has a weight average molecular weight (Mw) of about 500 to about 180,000, andwherein the fiberglass mat has 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.

Abstract
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.
