When the mass fraction of aziridine cross linker A was 3% in dry solid content of WPU emulsion, the water absorption of WPU pliofilm modified by different room temperature cross linker could be reduced to about 3%, and the WPU pliofilm had better permanent water resistance.

In this paper first a polyacrylamide with low molecular weight was synthesized,then the polyacrylamide was hydroxymethylated with formaldehyde,finally the hydroxymethylatcd polyacrylamide and acrylamidc reacted to form the cross-linking at room temperature polyacrylamide.

The influence of three different emulsion polymerization technologies, sop-free, micro-soap and conventional emulsion polymerizations on the ambient crosslinking acrylic emulsion paints based on diacetoneacyloamide (DAAM) as crosslinking monomer and adipic hydrazine as hardener.

No heat being needed in using, ambient crosslinking not only economizes the energy but also facilitates the application of coatings.

An aqueous ambient crosslinkable polymer acrylic emulsion was abtained by adding adipic acid dihydrazide(ADH) to the polyacrylate emulsion incorporating diacetone acrylamide(DAAM), and this emulsion was synthesized by seeded-emulsion polymerization.
