ABSTRACT:
The free formaldehyde content of the emulsion polymer, the amount of emitted formaldehyde and, even more particularly, of the finished nonwoven or textile may be substantially reduced by the use of a particular initiator system comprising a hydrophobic hydroperoxide and ascorbic acid. Moreover, this reduction in formaldehyde levels is accompanied by an unexpected improvement in the tensile properties of the emulsion binders.
