Double acetone acrylamide (Diacetone acrylamide), or DAAM, for a colorless, general commodities for needle crystal light yellow, pressed into flake its melting point, every 100 54 solubility in 25 g solvent soluble DAAM100g above the water, a alcohol, THF, ethyl acetate, such as CH2Cl2 soluble 98 g of styrene, in a nonpolar solvent CKS heptane, and petroleum ether in 30~ 60below 1 g only dissolve. DAAM molecules of acrylamide on double of free radicals can all get together, can also with many monomer copolymerization. DAAM ketone of carbonyl and alpha hydrogen can be ketone and lively DuoZhong reaction of hydrogen- So DAAM is a multi-function monomer. DAAM to rat oral half lethal dose for 1770 mg/kg LD50, skin and eye stimulate index is zero.
