Synthesis of ferrocene-modified poly(glycidyl methacrylate) and its burning rate catalytic property

A series of ferrocene-modified poly(glycidyl methacrylate) (PGMA-Fc) compounds were synthesized and applied as burning rate catalysts in simulative solid propellant to overcome migration problems. 1 H NMR and Fourier transform infrared spectroscopies and gel permeation chromatography were used to characterize the synthesized polymers. Their electrochemical behavior was evaluated using cyclic voltammetry. Their catalytic performance for the decomposition of ammonium perchlorate (AP) was investigated using thermogravimetric analysis. Anti-migration studies were conducted in migration tubes under 50°C. The results show that PGMA-Fc has a good catalytic effect on lowering the thermal decomposition temperature of AP. Anti-migration studies show that PGMA-Fc has better anti-migration performance than ferrocene and catocene.
