New polymeric material based on acrylamide-modified melamine resins were prepared and used as waterproofing agents. Synthesis and crosslinking steps, free formaldehyde content, and swelling and weight loss of cured samples are described. Acrylamide was used to enhance waterproofing properties of the products. The loss of weight of the acrylamide-modified melamine resin was examined after the resin had been heated for 30 min in boiling water, in relation to the curing time at 373 К or 393 K. Within 20 to 50 min, protraction of the curing time was found to result in advantageously smaller weight loss (Table 1, Fig. 2). The weight loss was found to be inversely related to the curing time. The data were processed by statistical methods using a Microsoft Excel Packet. The correlation factor was found to be -0.99.
