Based on the latest detailed mechanism of Dimethoxymethane (DMM), a new chemical kinetic mechanism model of Polyoxymethylene Dimethyl Ethers (PODE n ) with high degree of polymerization was preliminarily developed by extending reaction classes of DMM to PODE 3 with the same rate coefficient criterion. Compared with the existing PODE n model and experimental data, it was observed that the model of He could forecast the experimental data of PODE 3 accurately, but the prediction ability of the underlying DMM mechanism was poor. The model developed in this paper could forecast DMM experimental data accurately but could not forecast the experimental data of PODE 3 accurately. The same reaction classes of PODE n with different degree of polymerization did not have the same rate coefficient criterion.
