Irgacure

The photoinitiator selected for this study was 1-benzoyl cyclohexanol (Irgacure 184 from Ciba Geigy), a compound known for its high initiation efficiency and the weak coloration of its photoproducts. The multifunctional monomer was an epoxy-diacrylate derivative of bis-phenol A (Ebecryl 605 from UCB). A reactive diluent, tripropyleneglycol diacrylate, had to be introduced in equal amounts, in order to lower the viscosity of the formulation to about 0.3 Pa.s. [Pg.213]

Photoinitiators. Photoinitiators used include Darocur 1173 and Darocur 4265 which are 2-hydroxy-2-methyl-1-phenyl-1-propanone Irgacure 907, which is 2-methyl-1-... [Pg.220]

Initiator systems used to initiate photopolymerization with UV light generate radicals mostly by homolytic dissociation. Ketone acetals (e.g., Irgacure 651) absorb in the mid-range UV, dissociating to a benzoyl radical which initiates acrylate polymerization. The benzoyl group remains as part of the formed polymer (Eqs. 14 and 15). [Pg.333]

A TNT explosive was determined in the gas phase using an MIP-QCM chemosensor [127]. The MIP preparation procedure involved dissolution of an appropriate amount of the TNT template, MAA monomer, EGDMA cross-linker and Irgacure 369 [2-benzyl-2-dimethylamino-l-(4-morpholinophenyl)-butanone-l] photoinitiator... [Pg.217]

In another report, transparent channels (of width 500-200 pm and depth 50-180 pm) were filled with a photopolymerizable liquid mixture consisting of acrylic acid and 2-hydroxyl methacrylate (1 4 molar ratio), ethylene glycol dimethacrylate (1 wt%), and a photoinitiator (3 wt% Irgacure 651 or 2,2-dimethoxy-2-phenylacetophenone). Polymerization was completed in less than 20 s to produce the hydrogel structures [221]. [Pg.37]
