    摘要: UREA FORMALDEHYDE CONDENSATION PRODUCTS, SUITABLE FOR USE AS LONG LASTING FERTILIZERS, ARE PRODUCED IN A TWO STAGE CONDENSATION PROCESS, THE FIRST STAGE BEING A PRECONDENSATION STAGE CARRIED OUT UNDER ALKALINE CONDITIONS, AND THE SECOND STAGE BEING A MAIN CONDENSATION, CARRIED OUT UNDER ACID CONDITIONS. INTERMEDIATE THE TWO STAGES, THE REACTION MEDIUM IS COOLED, AND THE PH IS ADJUSTED TO THAT DESIRED FOR THE SECOND STAGE. THE PRODUCT OF THE SECOND STAGE IS DRIED, FOR EXAMPLE IN SPRAY DRIER, RAPIDLY AND AT A LOW TEMPERATURE WHEREBY AN INCREASE IN INSOLUBLE NITROGEN IS AVOIDED.

    摘要: WHEREIN R is selected from the group comprising hydrogen and an alkyl radical: R1 is selected from the group comprising hydrogen and a C1-C3 alkyl radical; R2 is selected from the group comprising hydrogen, methyl and ethyl radical; m is an integer from 0 to 1 and n is an integer from 0 to 1, and at least one nitrogen methylolated compound selected from the group comprising urea, its substituted derivatives and cyclic ureas.

    A copolymer cross-linking agent comprises at least one unsaturated N-substituted amide of an Alpha , Beta -unsaturated carboxylic acid which cannot be methylolated the substituent of which is an aliphatic moiety containing a diol-1,2 or -1,3 group, the amide corresponding to the general formula:
