Investigation on pyrolytic product distribution of low density polyethylene of hybrid rocket motor

According to working environment in the chamber of hybrid rocket motor,pyrolysis properties of low density polyethylene(LDPE) were investigated by means of pyrolysis gas chromatography(PGC),then experimental data of pyrolysis gas chromatography was analyzed.In comprehensive consideration of pyrolysis process,pyrolysis chemistry kinetics and pyrolysis product distribution,the model for pyrolysis product distribution of the LDPE was established by using statistic theory.Pyrolysis product composition and product relative content of LDPE under different temperatures can be obtained by means of the model.
