Processes based on different feedstocks for synthesizing polyoxymethylene dimethyl ethers were introduced, and the characteristics and the existing problems of each process were analyzed. No water formation or existence during reaction and the price of raw materials were important factors that determined the prcecess whether could be sucessfully applied in industrial production, and developping the process of synthesizing polyoxymethylene dimethyl ethers from methylal and anhydrous formaldehyde showed practical significance, however, reducing the cost of raw materials by developing new technologies should be done in future study.
