Hayashi, Naoki published the artcileSolubility of thermostable alkyl phosphate ester copper complexes in poly(alkyl methacrylate) for near-infrared-absorbing dyes, HPLC of Formula: 142-90-5, the main research area is solubility alkylphosphate ester copper polyalkyl methacrylate IR absorbing dye.
To realize thermoplastic near-IR-absorbing resin materials with weak absorbance in the visible region, the solubility of thermostable alkyl phosphate ester copper complexes in poly(alkyl methacrylate) was investigated for their use as near-IR-absorbing dyes. C4-C12 alkyl phosphate ester copper complexes were synthesized and mixed with Bu methacrylate, 2-ethylhexyl methacrylate, and lauryl methacrylate at 0.10 mol/g copper ion in the monomer solution The obtained solutions were polymerized to prepare 3 mm resin plates, and the plate transparency was evaluated by a haze meter. 2-Ethylhexyl methacrylate solutions of the 2-ethylhexyl phosphate copper complex and the isodecyl phosphate copper complex maintained their transparency even after polymerization, so these two copper complexes show good solubility in poly(2-ethylhexyl methacrylate). Both of the resin plates have >80% visible light transmittance and <50% solar direct transmittance. Thus, these resin materials are suitable as window materials that require heat-shielding properties and transparency. Polymer Journal (Tokyo, Japan) published new progress about Heat shields. 142-90-5 belongs to class esters-buliding-blocks, name is Dodecyl 2-methylacrylate, and the molecular formula is C16H30O2, HPLC of Formula: 142-90-5.
