Abstract

Procedimiento p ara la preparación de productos de condensación endurecibles de urea, formaldehido y aldehídos de CH-ácidas, que comprende la citada condensación en condiciones ácidas, reacción consecutiva con más formaldehido en condiciones neutras o alcalinas y eterificación posterior con alcoholes inferiores en condiciones ácidas, cuyos productos constituyen agentes de apresto en el tratamiento de géneros textiles que contienen al menos en parte, fibras de celulosa, caracterizado esencialmente por hacerse reaccionar, a temperatura de 50º C a 90ºC, 2 a 3 moles de urea con 0,9 a 1,1 moles de formaldehido y 1 mol de aldehido isobutárico en presencia de 0,2 a 1,0, particularmente 0,35 a 0,65.
