Procedure
About 100 parts by weight of the urea-urea condensate-sewer sludge produced in example 40 was mixed with 50 parts by weight of aqueous formaldehyde (35% formaldehyde) the heated to 70° to 80° C. for 20 minutes. The mixture solidified to form a solid formaldehyde-urea-urea condensate-sewer sludge resin.
Workup
- customproduced in example 40
