Abstract
By carefully adjusting the molecular weight and amounts of methacrylic acid and maleic acid and/or maleic anhydride comonomers in polyacrylic acid-based fiberglass binders, binder-treated fiberglass cured and B-staged product throughput may be maintained at production rates designed for phenol/formaldehyde binders due to the lower thermal requirements for cure as compared to homopolyacrylic acid-based binder systems.
