Acrylic Acid → Zinc acrylate

反応手順

In this experiment, acrylic acid was reacted with zinc carbonate to form zinc acrylate prior to addition of the other components. The reagent systems was prepared to contain 8% acrylic acid, 6.9% zinc carbonate, 0.25% MBA, 8% DMDHEU, 2% polyethylene softener, 0.1% wetting agent, and 0.5% K2S2O8. Samples of fabric that were impregnated with this reagent solution to wet pickups of approximately 110% were placed on pin frames in heat-resistant plastic bags that were flushed with nitrogen and sealed. In these bags, fabrics were subjected to 3 different curing conditions: (a) 120° C for 10 minutes followed 160° C for 5 minutes, (b) 120° C for 10 minutes followed by removal from bag and 160° C for 5 minutes, and (c) at 160° C for 15 minutes. The samples of fabric were rinsed extensively in hot-running tap water and line dried. Weight increases due to reaction of reagents were (a) 22.2%, (b) 23.6%, and (c) 21.7%; the DP appearance ratings for these 3 samples were 4.2, 4.5, and 4.3, respectively. The textile performance properties are summarized in Table I. In all three cases attractive levels of resilience and Accelerotor abrasion resistance were obtained. Sample (a) was tested and found to be 100% effective against S. epidermidis in the modified Quinn test.
