ABSTRACT:
Nonwoven mats or sheets having improved tensile strengths are prepared from a fibrous suspension of synthetic fibers thickened with a synthetic, addition polymer bearing pendant carboxamide groups and a cross-linking agent for the polymeric thickener. For example, a fibrous suspension comprising glass fibers, a polymer of acrylamide and a water-soluble hypohalite can be employed to prepare strong, glass fiber mats useful as effective reinforcement for roofing shingles.
