Optimization of process parameters of γ-polyoxymethylene synthesis

Two procedures for γ-polyoxymethylene production are considered: the existing commercial procedure and high-efficiency perspective procedure, differing in the chain-transfer agents and catalysts used. Mathematical models of the dependences of the yield and weight-average particle size of γ-polyoxymethylene on the synthesis process parameters for the commercial and perspective technologies are constructed using the method of optimum experiment design. The mathematical models were used for determining the optimum synthesis parameters allowing preparation of γ-polyoxymethylene with the weight-average particle size d ≤ 14 μm in maximal yields.
