Plasma styrene, monomer-copolymer

Figure 1. Monomer—copolymer composition relationship for the plasma-initiated copolymerization of methyl methacrylate with styrene. Plasma-initiated polymerization (%) NMR, (x) elemental analysis. Thermal polymerization (O) NMR, (Aj elemental analysis, (—) theoretical curve, tmma = 0.46 =...

Key a, oxygen plasma cleaned glass b, aluminum foil c, solvent cleaned rayon fibers d, solvent cleaned nylon fibers e, solvent cleaned wool fiber f, copolymer film (one monomer contains a chlorine substituted side chain) g, sulfonated 8% cross-linked styrene di-vinylbenzene copolymer beads h, copolymer containing diphosphine chelating...

Figure 13-13. Comparison of choice of sample preparation on MRM signal intensity of an investigation compound. The injection volume was 40pL.The count per second (CPS) signifies the detector (an electron multiplier) response. Protein precipitation (PPT), hydrophilic-lipophilic balanced co-polymer-based SPE (Oasis HLB- copolymer of styrene, divinylbenzene and -vinylpirrolidone monomers the hydrophihc refers to the NVP monomer, and the lipophilic refers to the SDVB monomers), and strong anion exchange SPE (Max) (all in 96-well plate format) were used in control rat plasma (unpublished data).
