Isotactic poly(methyl methacrylate) (it-PMMA)/syndiotactic poly(methacrylic acid) (st-PMAA) stereocomplex hollow capsules were fabricated by the deposition of stereocomplex films of it-PMMA and st-PMAA on silica particles by alternate layer-by-layer assembly and the subsequent removal of the silica particles with aqueous HF.

Polymethacrylate-based monolith with weak cation exchange functionalities was prepared in capillary column (i.d. 100 μm, o.d. 375 μm) by in situ polymerization of butyl methacrylate, ethylene dimethacrylate and N-methacryloyl-L-glutamic acid in presence of porogens. The porogen mixture included N,N-dimethyl formamide

We synthesized 8 polymethacrylate monolithic capillary columns using laurylmethacrylate functional monomer and various cross-linking monomers differing in the polarity and size. The efficiency of monolithic columns for low-molecular compounds significantly improved with increasing number of repeat non-polar methylene groups in

Gel dosimetry measures the absorbed radiation dose with high spatial resolution in 3D. However, recently published data show that the response of metacrylic-based polymer gels depends on the segmented delivery pattern, which could potentially be a considerable disadvantage for measurements
Jeremy Lee et al.
Journal of chromatography. A, 1270, 162-170 (2012-11-28)
We introduce a chromatography method for purification of large proteins and viruses that works by capturing them at a non-reactive hydrophilic surface by their mutual steric exclusion of polyethylene glycol (PEG). No direct chemical interaction between the surface and the
