    摘要: AN AQUEOUS MIXTURE OF LIGNOSULFONATE AND ISOPRENE RESIN GROUND TO PARTICULATE FORM HAVING A MELTING POINT OF 80-130*C. IN THE RATIO OF LIGNOSULFONATE TO ISOPRENE RESIN IN THE RANGE OF 0.5:1 TO 4:1 BASED ON DRY WEIGHTS, SAID LIGNOSULFONATE AND ISOPRENE RESIN BEING MIXED IN THE PRESENCE OF FROM 0.1 TO 5% BASED UPON THE DRY WEIGHTS OF A UREA FORMALDEHYDE RESIN HAVING A VISCOSITY RANGE OF 200 TO 1500 CENTIPOISES PRIOR TO INTERMIXING WITH CELLULOSIC FIBERS.
