N-Methylol Acrylamide 48 (NMA 48)




NMA 48 contains N-Methylol Acrylamide, offered as a 48% aqueous solution. Its reactivity due to a bi-functional both vinyl and hydroxyl-methyl groups. Polymers can be formed through varying conditions via emulsion, solution, or suspension techniques. The hydroxyl-methyl groups, are self-cross-linkable under moderate conditions which can be reacted separately by varying the reaction conditions. The hydroxyl-methyl group can be first be reacted with a substrate like cellulose and subsequently cross-linked by free radical polymerization.

NMA48 is highly reactive, thus, it is essential that precautions must be taken to maintain stability during shipping and storage. It is recommended that NMA48 is used before 12 months from the date of manufacture and should be stored in a cool place where the temperature is below 31°C. Shelf life may be reduced if these storage are not observed.

NMA 48 is a reactive monomer. Strict conditions should be well maintained and controlled:  



As supplied, NMA 48 has a pH of 6.0 to 7.5. Modification of the pH range can reduce the stability. Monitoring of pH is recommended and it should be adjusted with phosphoric salt or acid. 


NMA48 should be controlled to between below 31°C.  At temperatures below –10°C NMA48 will crystallize. Slowly warming the product will re-dissolve the crystals.  Avoid to apply direct steam or heat. At temperatures above 50°C (120°F), slow polymerization will be initiated over time.  At temperatures above 85°C (120°F), spontaneous polymerization may run.  


Dissolved oxygen will inhibit polymerization of NMA 48.  


Peroxides such as persulfate, strong base and sulfite (under certain condition) can initiate polymerization of NMA 48.
