| Abstract: | Three
quaternary ammoniums with polymerizable group, methacryloxylethyl benzyl dimethyl ammonium
chloride(MBDAC), methacryloxylethyl butyl dimethyl ammonium bromide(MBDAB),
methacryloxylethyl ethyl dimethyl ammonium bromide(MEDAB) are synthesized and
characterized by infrared spectra, elemental analysis and nuclear magnetic resonance.
Homopolymer of MBDAC and its copolymers with methyl methacrylate and styrene are
synthesized by radical polymerization and characterized by elemental analysis, GPC and
infrared spectra. DSC and TG measurements show that glass transition temperature and
tensile strength of the copolymers of MMA or styrene with 10%(mol) MBDAC are higher than
those of PMMA and PS. |
