Polyoxymethylene Microparticles and Methods of Production and Use Thereof
1 Dec 22
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. (TBP+10C) of the one or more solvents) to form a polymer mixture, wherein a difference in total Hansen solubility parameters (Δδt) 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.
