摘要: Abstract Styrene-(methacrylic acid) random copolymers with various contents of methacrylic acid were studied by dynamic mechanical spectroscopy. From experimental data obtained under isothermal conditions, a physical model behaviour near Tg such was established. Such theoretical approach quantitatively points out changes in molecular motion macromolecular chains brought about acid. these results, it concluded that hydrogen bondings between segments, induced the presence acid, could act as ties network.
