Web1 day ago · In this work, we achieved the synthesis of the alternating copolymer composed of commodity monomer units, methacrylic acid (MAA) and acrylonitrile (AN… Webn of the polymers were also measured by SEC (Shodex GPC-104) in THF at 40 oC (flow rate: 0.3 mL/min). In the SEC system, three linear-type polystyrene gel columns (Shodex LF-404: exclusion limit = 2 ´ 106; particle size = 6 µm; pore size detector, and a UV-41 ultraviolet detector set at 250 nm (all from Shodex). Webpolystyrene-gel columns (Shodex LF-404) at 0.35 mL/ min of flow rate. The columns were calibrated against 12 standard poly(St) samples (Tosoh, PS-Oligomer Kit; M w = 500–1090000; M w/M n = 1.01–1.14). For the analyses of cyclic initiators, TOSOH H2000 column was used instead of LF-404. Preparative SEC kathryn moore dentist peterborough
