Abstract

The UV-curing of ultra-thin films of acrylate monomers on Al 2O3 particles has been studied by using photo-differential scanning calorimetry (photo-DSC). This fundamental study is necessitated by the need to optimize the UV-curing of coated particulates in air-driven fluidized beds. The effects of chemical structures of monomers, thickness of the films, type of initiators, and the presence of oxygen on the curing were investigated. Results show that the photo-polymerization of the ultrathin films on the particles is much more sensitive to oxygen poisoning than the thick films on flat surfaces and the conversions of monomers greatly depend on the types of monomers and initiators used. Esacure 1001M, a sulfurcontaining benzophenone, has been used together with 2-ethylhexyl-4-dimethylamino benzoate (Esacure EHA) as the initiation system to reduce the oxygen poisoning effect.
