Ł¨acryloyl morpholineˇ˘4-acryloyl morpholineŁ©
acmo (acryloyl morpholine) has been used for uv and eb curable resins (primarily inks and coatings) in japan for 10 years. it has been found that acmo displays similar properties as other reactive diluent monomers, such as n-vinyl-2-pyrrolidone (nvp), but exceeds them in performance and safety. although it is a monofunctional monomer of heat resistance, but it shows very little irritation on skin (p.i.i=0.5). its vapor pressure is also low and scarcely lets out the irritating odor.
¨’acryloyl morpholine homo-polymer is superior in solubility and soluble in various solvent.
¨’acmo (acryloyl morpholine) has a good compatibility with oligomers, multi-functional acrylates, and resin components.
¨’acryloyl morpholine has a quicker hardening speed in the polymerization process than isobornyl acrylate and phenoxyethyl acrylate.
¨’low viscosity and low vapor pressure.
¨’uv, eb curable resins made with acryloyl morpholine have a low hygroscopicity and good resistance to alkali, acids, and solvents.
¨’acryloyl morpholine has good retention and elongation stability.
¨’lower odor and color contribution than other diluent monomers.
¨’acryloyl morpholine has a nitrogen radical, which prevents generation of ozone inhibiting polymerization.
¨’acryloyl morpholine can keep good dimensional stability of uv, eb curable resins
