Binder compositions and methods for making and using same

A binder composition, comprising:

• a free radical precursor;
• and
• an unsaturated polyamide prepolymer, wherein:
• the free radical precursor comprises a mixture of hydrogen peroxide and a catalyst,
• the catalyst comprises a metal ion bound to a complexing agent,
• the metal ion comprises iron, copper, manganese, tungsten, or molybdenum,
• the complexing agent comprises cyanide, sulfate, ethylenediaminetetraacetic acid, ethylenediamine-N,N′-disuccinic acid, ethyleneglycol bis(2-aminoethylether)-N,N,N′,N′-tetraacetic acid, diethylenetriaminepentaacetic acid, trans-1,2-diaminocyclohexane tetraacetic acid, iminodisuccinate, or nitrilotriacetic acid,
• the unsaturated polyamide prepolymer comprises a reaction product of a polyamine and a polyacid or a reaction product of a polyamine and an ester, and
• the binder composition comprises about 10 wt % to about 80 wt % of the hydrogen peroxide and about 0.01 wt % to about 20 wt % of the catalyst, based on a combined weight of the unsaturated polyamide prepolymer and the free radical precursor.

A binder composition, comprising:

• a free radical precursor;
• an unsaturated polyamide prepolymer;
• and
• a reactive monomer, wherein the reactive monomer comprises styrene, methyl styrene, chlorostyrene, vinyl toluene, divinyl benzene, vinyl acetate, acrylic acid, methacrylic acid, a lower alkyl ester of acrylic acid, a lower alkyl ester of methacrylic acid, diallyl phthalate, a vegetable oil, or any mixture thereof.
