Self-crosslinking aqueous polystyrene-butadiene dispersions for consolidating bituminizable nonwovens and also consolidated nonwovens

摘要

Self crosslinking aqueous polymer dispersions containing hard and soft copolymers containing polymerized units of a conjugated diene, a vinyl aromatic compound, an organic carboxylic acid and/or anhydride, and at least one crosslinker may be included in consolidated nonwoven constructions. The consolidated nonwoven construction is useful as a base material such as a bituminized roofing mat.
