Synthesis of poly(2-(methacryloyloxy) ethyl ferrocene carboxylate-co-methacrylic acid)s and their anti-migration and burning rate catalytic properties

A series of copolymers of poly(2-(methacryloyloxy) ethyl ferrocene carboxylate- co -methacrylic acid)s (P(FHEMA- co -MAA)s) were synthesized as burning rate catalysts (BRCs). Their structures were verified using proton nuclear magnetic resonance ( 1 H NMR) and Fourier transforms infrared (FT-IR) spectroscopy. The electrochemical behavior of P(FHEMA- co -MAA)s was investigated by cyclic voltammetry (CV). The CV results indicated that P(FHEMA- co -MAA)s showed redox behavior. Anti-migration test proved that P(FHEMA -co- MAA)s possesses better anti-migration properties than ferrocene (Fc) and 2, 2-bis (ethylferrocenyl) propane (Catocene). The burning rate (BR) catalytic effect of P(FHEMA -co- MAA)s on thermal decomposition of AP was examined through thermogravimetry (TG) and differential thermogravimetry (DTG). P(FHEMA -co- MAA)s were found to have high catalytic effects in accelerating thermal decomposition of ammonium perchlorate (AP).
