ABSTRACT:
Non-formaldehyde emitting binders for nonwoven cellulosic materials comprise a solution copolymer of an olefinically unsaturated organic compound having at least one carboxylate group conjugated with the olefinic linkage, which is reacted with a hydroxyalkyl ester of an olefinically unsaturated carboxylic acid. The product of said reaction is admixed with a non-formaldehyde containing latex carrier to produce a binder composition which will reach substantially fully cured wet strength in 8 seconds or less.
