    摘要: Methods include dissolving a polyoxymethylene (POM) homopolymer or copolymer in one or more solvents at an elevated temperature (e.g., up to a boiling point+10°C (T BP+10C ) of the one or more solvents) to form a polymer mixture, wherein a difference in total Hansen solubility parameters (Δδ t ) for the POM homopolymer or copolymer and the one or more solvents is 6 or less; cooling the polymer mixture to form a POM particle composition; and isolating the POM particle composition. Said method may be performed at ambient pressures.
